What is the relationship between electric potential and a wire in an electrical circuit?
The electric potential in a wire in an electrical circuit is the amount of electric potential energy per unit charge. As the wire carries current, the electric potential decreases along the wire due to the resistance of the wire. This relationship is described by Ohm's Law, which states that the electric potential difference across a wire is directly proportional to the current flowing through it and inversely proportional to the resistance of the wire.
What is the potential difference across a 5.0 W resistor that carries a current of 5.0 A?
There's no way to tell with the given information. "5 W" tells the maximum power the resistor can dissipate without overheating and possibly becoming damaged. That rating doesn't tell you anything about the power it's actually dissipating, or its resistance. Knowing either of those numbers in addition to the current through it would allow you to calculate the voltage across the component. The voltage across it is (5 times its resistance) or (0.2 times the power it's dissipating).
What carries the electric charge around a metal wire?
When metals bond they form a metallic bond. In a metallic bond the electrons from the outer shell of metals atoms become delocalised and the remaining ions sit in a sea of disassociated electrons.This sea of electrons can flow freely. As the electrons gain kinetic energy from a heat source thus they move more vigorously around the metal and transmit the kinetic energy from electron to electron and ion to ion. This is why metals conduct heat.When a potential difference is applied across a wire it causes the electrons to flow. It is movement of the electrons with their negative charge that carries electricity through a wire.
What is The Voltage Of each wire in Straight 220V Circuit?
Voltage is not an absolute figure. Voltage Difference is the exact term. So, the voltage difference between the two wires in the 220 V circuit will be 220V.
What carries electricity through a wire?
Electricity is carried through a wire by the flow of electrons. When a voltage is applied across the wire, the electrons move in response to this, creating an electric current that can power devices or light bulbs.

What is the resistance of a conductor that carries a current of 120 amperes when the potential difference between its ends is 240 volts?
The resistance of the conductor can be calculated using Ohm's Law: resistance (R) = voltage (V) / current (I). Plugging in the values gives: R = 240 V / 120 A = 2 ohms.
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
What does carry electrical currents?
An electric current carries electrons from an area of high potential to another area of low potential. Potential difference is the condition that must exist for a current to move electrons around.
What is the potential difference between the terminals of 10 ohms resistance which carries of current of 3 ampere?
Ohm's Law: Voltage is current time resistance3 amperes through ten ohms is 30 volts.Note: This is also 90 watts, enough power to generate heat. Resistance is a function of temperature, so things will change as the resistor gets hot.

What is the definition of the resistance arm?
The resistance arm is the side of the lever (from the fulcrum to the load) that carries the load.

nuclear :)
What is the difference between a cop and a fire fighter?
Only a cop carries a handgun.

What does the resistance of a circuit mean?
Resistance in a circuit is its ohmic value of the circuit. It is comprised of all of the devices and components that make up the circuit. This also includes the wire that carries the voltage to the load of the circuit.
