Question

define the electric resistance of a wire.

Answer 1

The electrical resistance of a circuit component or device is defined as the ratio of the voltage applied to theelectric current which flows through it: If the resistance is constant over a considerable range of voltage, then Ohm's law, I = V/R, can be used to predict the behavior of the material.

Answer 2

An electric resistance is defined as the restriction to the flow of current in the wire. When there is maximum collision take place between electrons and atoms, it will increase the resistance of an object.

It is measured in units of ohms. The formula used to find resistance is:

Resistance = pL/A
