The question is meaningless. Voltage is a measure of electrical pressure, so it must be measured between two points.

In many systems, the chassis is used to complete the circuit by providing a return path. In most automotive or truck applications, this is the case. This saves materials cost by needing fewer wires.

In those systems, the voltage is measured between ground and the point of interest, but if there is a break in the path along the chassis, the results will be unreliable.

You need to know the Primary and secondary voltages to do the calculation.

we only have 100Kva transformers on our salt furnaces as an example:

100000va / 12v = 8333 amps the secondaries , wire, and electrodes are water cooled.

A mica capacitor is simply one that uses the mineral mica as the dielectric or insulator between plates.

Bipolar junction transistors has two junctions base emitter junction, base collector junction. Accordingly there are four different regions of operation in which either of the two junctions are forward biased reverse biased or both. But the BJT can be effectively operated in there different modes according to the external bias voltage applied at each junction. i.e. Transistor in active region, saturation and cutoff. The other region of operation of BJT is called as inverse active region.

1.3.3 Automatic sweep mode; 1.3.4 Recurrent sweeps; 1.3.5 Single sweeps ... The basic oscilloscope, as shown in the illustration, is typically divided into translucent windows in the panel to illuminate different parts of the sensitivity scale.

A VERY BIG PROBLEM practically all electronics are restricted to voltages no greater 40 50 volts electrostatic can be as much as 5kv to 50 kv but the source impedance is very hi so while the voltage is there current capabilities are not a low impedance device can possibly survive these discharges but a hi impedance device like MOS cannot survive since the negligent current will raise the potential very hi blowing the device.

ANSWER:Imagine that all the elements of a simple circuit (such as a battery, a light globe , a switch, and a resistor ) When the switch is closed , the electric current flows round and round the circuit just the same way as water would flow through these elements if the circuit had a Water pressure supply and a thin section of pipe and then a thick section of pipe etc . The FLOW of the electricity in Amps can be thought of as the same thing as the Flow rate of water in a pipe system. The Ammeter, is put into the circuit between any 2elements of the circuit, so that the current flows through it , as well as all the other elements (parts) of the circuit. When current flows through the various elements the flow rate (Current) is the same in all of them. As the current flows through, there is a drop of pressure (Voltage) as the electrons flow through each of the elements of the circuit. The actual pressure(volts) in each piece of the circuit , can be measured, by placing a Voltmeter across any individual item in the circuit. The drop in pressure at each item is measured by connecting each terminal of a Voltmeter across the item you are dealing with. The voltage across the 2terminals of the supply will be perhaps 12 Volt(a car battery) The volts ' pressure ' across the globe may be say 8 volt and the volts across the switch may be 3volts and the volts across the resistor may be only 1 volt. Always think of Ampere, as 'Flow Rate', and think of Voltage as ' Electric Pressure' If a circuit has a spot where it splits into 2 separate circuits , and then turns back into 1 piece of circuit, the current flowing as it goes into the 2 different passages, is split up, or shared between the 2 passages, and then the 2 separate currents join together again as they re-enter the single part of the circuit. To find out the current flow in each of the 2 parallel parts of the circuit you must place the Ammeter in series within each of the 2peices of circuit . The 2 separate curent readings will have a total equal to the current reading in the main single passage circuit.

Oddly enough, it's called an A to D Converter and has many sources to obtain, including build it yourself plans or online auctions. There is also D to A converters so please be sure you pick the correct converter.

Answer: it will burn out

**Explain:**The same current flows through each part of a series circuit. If the circuit is broken at any point there won't be any current that will flow. In this case, if one of the bulbs blew out, the other bulb would not be able to light up because the flow of electric current would have been interrupted.

The forward resistance of a diode is, by Ohm's law, the voltage across the diode divided by the current through the diode. Note that, since diodes are non linear, the effective resistance is not constant over all possible voltages and currents.

One can find circuit board wallpaper from the Apps Zoom website. The website has a variety of wallpapers offered, including some circuit board wallpapers.

1) The devices used in digital circuits generally operate in one of the two unites, known as ON and OFF resulting in a very simple operation.

2) There are only a few basic operations in digital circuits which are very easy to understand.

3) Digital techniques require Boolean algebra which is very simple and can easily be learnt.

4) Digital circuits require basic concepts of electric network analysis which can easily be learnt. The principal electrical char¬acteristics required are switching speed and loading considerations. On the other hand, analog circuits and systems involve frequency and time domain concepts, complicated circuit analysis techniques, etc. which make the un¬derstanding of these circuits much more difficult than the digital circuits.

5) A large number of IC's are available for performing various operations. These are highly reliable, accurate, and small in size and the speed of operation is very high. A numbers of programmable IC's are also available.

6) Various IC's are available in a logic family with similar electrical character¬istics which make the design and development of digital systems very simple and also reduce interfacing problems. Also, a number of logic families based on different technologies are available which help in optimizing the system design from the point of view of power requirement and speed of operation.

The electrons flows from negative to positive and then positive to negative.The pole of the flow of electron changes at a time interval.This is called alternating current (AC).

The current through the circuit is directly proportional to the voltage across the circuit.

The proportionality constant is 1/R, where 'R' is the total effective resistance of the circuit.

C = V / R

V = C R

R = V / C

To prevent the equipments from lightning strokes. Because the cloud is negatively charged at bottom it requires a zero or a positive potential to discharge, and it selects the ground (Zero potential) to discharge. If the Telecom Equipments are fed with positive the cloud will choose the low resistance tallest positively charged Antenna's to discharge, this could damage the entire setup of Telecom equipments. So the Telecom equipments are fed with Negative supply Voltage.

Bandwidth is the measure of range or band of frequencies that a channel or path can handle at a maximum rate.

whereas, throughput is the average rate of successful message delivery over a communication channel.

and Goodput is simply the changing in throughput rate.

The nearest AWG wire size to 50 sq. mm is 1/0.

A 1/0 aluminium conductor with an insulation factor of 75 or 90 degrees C is rated at 180 and 205 amps respectively.

This would be the "AND" operator. 1 AND 1 = 1.1 AND 0 = 0.

0 AND 0 = 1

This is not advised! The 9-volt charger might have a current limiter so that nothing burns up, but it any case if left on it will destroy the 6 volt battery by overcharging. A 6-volt charger is not expensive.

to assemble a circuit you just need to connect one end of a wire to the battery and the other to the light bulb ( could be another electrical device) now take an other wire and connect on end of it to the other side of the battery and the other to the other side of the light bulb( or an other electrical device. if your circuit is including a switch this is how you do it: ( you will need three wires for this circuit if you have one electrical device)

connect one end of the wire to the battery and the other to the switch.Grab another wire and attach one end of it on the other side of the switch and the other to the electrical device (light bulb). Grab another wire and attach one end of it to the other side of battery and the other to the other side of your electrical device. And there you have it how to assemble a circuit
