Question

What is the unit of potential difference?

Answer 1

Determine the unit of potential difference.

1. The quantity of effort done in transporting a unit charge from one location to another is known as potential difference.
2. A supply's potential difference (or voltage) is a measurement of such energy delivered to charged carriers inside a circuit.
3. Whenever a coulomb charge at any location has high potential energy, the point has a high electric potential.
4. Therefore, if a coulomb charge at a place has low potential energy, which point has a low electric potential.
5. This electrical potential difference is the difference in electric potential between the two places.

Mathematical representation:

$dv=\frac{dw}{dq}$

$1Volt=1\frac{Joule}{Coulomb}$

Hence, the unit of potential difference is volt.
