Voltage

Currently, we are in a day and age when reducing our energy consumption is a primary goal for all. This is a priority that all must take into consideration, no matter if you own your own business, home or you are renting. Anything we can do to decrease in daily energy consumption is not only a benefit to our wallets but also to society as a whole. One way to achieve these primary goals of reducing

Contactless AC Mains Voltage DetectorThis is a CMOS IC (CD4033) based circuit which can be used to detect presence of mains AC voltage without any electrical contact with the conductor carrying AC current/voltage. Thus it can be used to detect mains AC voltage without removing the insulation from the conductor. Just take it in the vicinity of the conductor and it would detect presence of AC voltag

Description: In many low-voltage applications, undesired voltage overshoots may occur at the input during the circuit operation. To avoid the harm of this overvoltage, we generally use parallel clamps such as fuses or other current limiting devices. The disadvantage of the parallel protection may be resetting or renewing the protector component. This circuit provides a series protection th

Thermionic Emission A thermionic energy converter is a device consisting of two electrodes placed near one another in a vacuum. One electrode is normally called the cathode, or emitter, and the other is called the anode, or plate. Ordinarily, electrons in the cathode are prevented from escaping from the surface by a potential-energy barrier. When an [...]

Photoelectric Effect Light is a form of energy and is considered by many scientists to consist of small particles of energy called photons. When the photons in a light beam strike the surface of a material, they release their energy and transfer it to the atomic electrons of the material. This energy transfer may dislodge electrons [...]

Thermoelectricity Some materials readily give up their electrons and others readily accept electrons. For example, when two dissimilar metals like copper and zinc are joined together, a transfer of electrons can take place. Electrons will leave the copper atoms and enter the zinc atoms. The zinc gets a surplus of electrons and becomes negatively charged. The [...]

Piezoelectric Effect By applying pressure to certain crystals (such as quartz or Rochelle salts) or certain ceramics (like barium titanate), electrons can be driven out of orbit in the direction of the force. Electrons leave one side of the material and accumulate on the other side, building up positive and negative charges on opposite sides, as [...]

Magnetic Induction A generator is a machine that converts mechanical energy into electrical energy by using the principle of magnetic induction. Magnetic induction is used to produce a voltage by rotating coils of wire through a stationary magnetic field, as shown in Figure 13, or by rotating a magnetic field through stationary coils of wire. This [...]

Static Electricity Atoms with the proper number of electrons in orbit around them are in a neutral state, or have a “zero charge.” A body of matter consisting of these atoms will neither attract nor repel other matter that is in its vicinity. If electrons are removed from the atoms in this body of matter, as [...]

Electrochemistry Chemicals can be combined with certain metals to cause a chemical reaction that will transfer electrons to produce electrical energy. This process works on the electrochemistry principle. One example of this principle is the voltaic chemical cell, shown in Figure 11.

Most ohmmeters of the design shown in the previous section utilize a battery of relatively low voltage, usually nine volts or less. This is perfectly adequate for measuring resistances under several mega-ohms (MΩ), but when extremely high resistances need to be measured, a 9 volt battery is insufficient for generating enough current to actuate an electromechanical meter movement. Also, as discussed in an earlier chapter, resistance is not always a stable (linear) quantity. This is especially true of non-metals. Recall the graph of current over voltage for a small air gap (less than an inch): While this is an extreme example of nonlinear conduction, other substances exhibit similar insulating/conducting properties when exposed to high voltages. Obviously, an ohmmeter using a low-v

Embedded systems that are dealing with DAC require a good voltage references.

Let's take another look at our example series circuit, this time numbering the points in the circuit for voltage reference: If we were to connect a voltmeter between points 2 and 1, red test lead to point 2 and black test lead to point 1, the meter would register +45 volts. Typically the "+" sign is not shown, but rather implied, for positive readings in digital meter displays. However, for this lesson the polarity of the voltage reading is very important and so I will show positive numbers explicitly: When a voltage is specified with a double subscript (the characters "2-1" in the notation "E2-1"), it means the voltage at the first point (2) as measured in reference to the second point (1).

The use of variable voltage for instrumentation signals seems a rather obvious option to explore. Let's see how a voltage signal instrument might be used to measure and relay information about water tank level: The "transmitter" in this diagram contains its own precision regulated source of voltage, and the potentiometer setting is varied by the motion of a float inside the water tank following the water level. The "indicator" is nothing more than a voltmeter with a scale calibrated to read in some unit height of water (inches, feet, meters) instead of volts. As the water tank level changes, the float will move. As the float moves, the potentiometer wiper will correspondingly be moved, dividing a different proportion of the battery voltage to go across the two-conductor cable an

A voltage multiplier is a specialized rectifier circuit producing an output which is theoretically an integer times the AC peak input, for example, 2, 3, or 4 times the AC peak input. Thus, it is possible to get 200 VDC from a 100 Vpeak AC source using a doubler, 400 VDC from a quadrupler. Any load in a practical circuit will lower these voltages. A voltage doubler application is a DC power supply capable of using either a 240 VAC or 120 VAC source. The supply uses a switch selected full-wave bridge to produce about 300 VDC from a 240 VAC source. The 120 V position of the switch rewires the bridge as a doubler producing about 300 VDC from the 120 VAC. In both cases, 300 VDC is produced. This is the input to a switching regulator producing lower voltages for powering, say, a personal com

The VCO is based on a Hartley oscillator. The frequency is determined by L1 and capacitor C1. The Vtuning voltage will change the capacitance in the varactor BB132 wich will change the oscillation-frequency. The value of capacitor C2 will determine how much the frequency can be changed by the tuning voltage. The larger value the more the frequency will change. This VCO is based on two dual-gate FET. First FET is a Hartley oscillator where the frequency is determined by the value of L1, C1, C2 and the varicap diod. C2 set the span of the VCO. The second FET is just an amplifier. The gain is less than 1, but the current will be higher and the oscillator will not be loaded. The output amplitud changes depending on the frequency and how many turns there is on L1. By changing the voltage on g2

is an electrical regulator designed to automatically maintain a constant voltage level.It may use an electromechanical mechanism, or passive or active electronic components. Depending on the design, it may be used to regulate one or more AC or DC voltages.With the exception of shunt regulators, all modern electronic voltage regulators operate by comparing the actual output voltage to some internal fixed reference voltage. Any difference is amplified and used to control the regulation element. This forms a negative feedback servo control loop. If the output voltage is too low, the regulation element is commanded to produce a higher voltage. For some regulators if the output voltage is too high, the regulation element is commanded to produce a lower voltage; however, many just stop sourcing

"Dielectric" is a broad term-it can involve both gases, liquids and solids. I've just read 908725376.Ph, and there the discussion of focused on gases, so I'll restrict this discussion to gases. There are in fact two main mechanisms by which light can influence the breakdown processes: the first is called photo-ionization, and the second is called tunnel ionization. I'll briefly outline both processes. I'd like to note beforehand that the second process is rather exotic. Furthermore, I'll simplify things a bit, so First, let's define what we mean by breakdown. A normal gas at typical atmospheric conditions consists of uncharged molecules. In order to be able to conduct current, this gas will have to be at least partially split in negative and positive charges. Normally, this involves rippin

By Jestine Yong The complaint for this LIKOM 15” L4031NDG Monitor was no display and has power. Well, no display can be no high voltage, failure in G1, G2 and heater circuit, defective flyback transformer, failure in picture tube and microprocessor or many other reasons . In order to find out the answer we have to switch on the Monitor. Upon switching on the monitor, I could not hear any sound from the monitor but the power led is on (green light). You can’t feel any static at the glass of the picture tube. This could be a sign of no high voltage symptom.Anyhow, I have to use my faithful Kaise SK9000 high voltage probe to check if the high voltage present at the anode. Sometimes if you can’t feel the static at the glass of CRT, doesn’t mean that the high voltage is not present. It’s only low in high voltage; say may be 10 to 12 kilovolts. Low high voltage and no high voltage are totally two different symptoms. In the above case, my high voltage probe registered zero volts! So

By Jestine Yong By only knowing how to read electronic schematic diagram and testing electronic components were not enough to make us a good electronic repairers. Many faults can’t be detected even if you know how to accurately test and check all the electronic components because those faults only can be detected by simply performing a voltage test. Do you know that quite a numbers of Monitor problems I have to perform a voltage test in order to locate the defective components? Yes, if without voltage testing, I might end up can’t find the fault and the Monitor have to be return back to customers. What if you return many Monitors back to the same customers? Of course your business reputation would be affected and worst if your competitors (other electronic repairers) be able to repair it. You would definetely lose out the customers and is very difficult to get back his trust again about your capability to repair Monitors.I do know lots of electronic repairers especially newbie’s

A friend of mine is selling his older Vivitar 285 Flash, 'Good Condition', slightly used, dropped only a few times, I swear ! He only wants $50.00 Dollars ( US ) to part with it forever, so I may have to help him out and add it to my camera bag. The 285 is a highly regarded portable flash, considered a dependable workhorse that has earned its place in photo equipment history. Cheap, tough and easy to use, with accuracy from its non E-TTL sensor that still outperforms some of those fancy newer $400.00 units. And all that for a fitty! That got me thinking about my Canon and the voltage sync compatibility problems with some of the newer Digital Cameras.I believe it's safe to use the 285 HV unit on any Canon Digital Camera, but the older 285 ( Non HV ) may fry your DSLR. Checking the voltage sync will be the safest and easiest way to guarantee that I don't cook any of my camera's electronics.

 This is a pulse-mode transformer circuit that I have some experience with. I used this successfully in combination with a Polaroid transducer. Introduction The circuit can be used to generate a voltage of about 70V using a current of about 4 mA @ 6V input voltage. The use of an easily available stroboscope trigger coil makes it quite small. How it works The integrated circuit is a 7555 generating a 50/50 square wave of around 100 kHz. The square wave’s rising edges momentarily trigger the transistor into conduction, causing current to flow through the primary of the stroboscope transformer. The current pulse in the primary causes a much larger voltage pulse in the secondary of the transformer, thereby charging the output capacitor through the diodes. Components I’m using the 7555 (CMOS variety of the NE555) to generate the square wave, because it behaves much better with respect to power supply transients than the NE555. The circuit topology used here makes it possible t

Here is a simple circuit for generating over 100 volts from a 12 volt source for powering low current devices and experiments. The two transistors may be 2N4401 and 2N4403 or similar for lower power applications or higher power devices for heavier loads. If more power is desired then lower the two 10 ohm emitter resistors to 3.3 ohms. When driving power transistors, more drive may be achieved by adding two more gates and resistors in parallel with the two output gates shown. Notice that the two driver gates are simply in parallel with 220 ohm current limit resistors in series with their outputs. The transformer is an ordinary power transformer but selecting a secondary voltage somewhat below the power supply voltage will give higher output voltage. The frequency is set near 60 Hz by the two 1 Meg. resistors and the 0.01 uF capacitor and this frequency may be varied for driving an audio transformer. The circuit will work well with other power supply voltages but do not exceed the volta
