Question

State the plugical quantity which is equal to the ratio of potential difference and current? Define si unit

Answer 1

Electrical Resistance, R = V/I

The Resistance of a conductor is said to be one ohm (Ω) if the potential difference applied across its ends is 1 volt and the current of 1 A flows through it. It SI unit is ohm (Ω).

1 ohm = 1 volt/1 ampere.

Extra Information :-

One Volt Potential Difference - The potential difference between two points in an electric field is the amount of work done in bringing a unit positive charge from one point to another.

Potential Difference = Work done/Charge = W/Q
