Question

State and define the S.I unit of potential difference.

Answer 1

The S.I. Unit of potential difference is Volt.
It is the difference of potential that would carry one ampere of current against one ohm resistance.

Answer 2

Answer:

The SI "Unit of potential difference" is Volt. It is "the difference of potential" that would carry "one ampere of current" against one ohm resistance.

Explanation:

The electrical potential between two points is called potential difference. The S.I unit of potential difference is volt. One volt is equal to the energy consumed by one joule per electric charge. Volt is the "derived unit" for electric potential. The potential difference that carry 1 ampere of current will be against one ohm of resistance.
