What is the measure of the voltage decrease along a wire?

Decrease or reduction of voltage along the wire is called voltage drop. It is measure through wire and load resistance difference.


Why is a resistor called so?

I resistor is called so because it provides electrical resistance (measured in ohms). Electrical resistance describes how an electrical conductor (a wire) opposes the flow of an electrical current (flow of electrons). To overcome this opposition a voltage (a energy) must dropped (used) across the conductor (wire).


What is a current-carrying wire?

A wire with some resistance and a voltage applied to it The amount of current I passing this wire is V/R


For voltage to be induced from one stationary wire to another one wire must have a n what type of current flow?

Intermittent. Faraday's law tells us that voltage can only be induced in a second coil when the current in the first coil changes


What is Faraday's law?

Overall, induced voltage is proportional to the product of the number of loops of coiled wire and the rate at which the magnetic field changes


Which wire carries the voltage?

In an electrical circuit, the wire connected to the positive terminal of the voltage source carries the voltage. This wire is usually indicated by the color red in standard wiring practices.


Is cat5 wire considered low voltage?

Yes. cat6 is low voltage / signal wire.


Does the type of wire make a difference to the circuit?

yes. If you use wire of certain resistance first the get the result and if u use other wire which is of more or less resistance then the voltage drop in the wire changes so the output also changes. Yes it does, but the difference may be inconsequential. The specific circuit in question and type of wire should be included for a specific answer.


How do you check voltage in an exposed wire?

To check the voltage in an exposed wire, you can use a digital multimeter in voltage measurement mode. Ensure the wire is not connected to any power source, then carefully touch the multimeter probes to the exposed wire's metal contacts. The multimeter will display the voltage present in the wire.


The voltage drop in line can be decreased by?

In an IEC-320 plug which wire carries electrical voltage?

the hot wire carries the electrical voltage


What happens to voltage when wire length increase?

When the length of the wire increases voltage drop across the wire will occur.There are two factors that can result in voltage drop. One diameter of the wire, two length of the wire.Voltage drop increases with increase in length of wire, whereas voltage drop decreases with increase in diameter (cross section area) of the wire.G.RAOAnswerIf you are asking what happens to the voltage across a length of wire when its length increases, the answer is nothinghappens! The voltage applied to the wire is determined by the supply, not by the load (i.e. the wire).
