Question

What do you understand by the terms potential difference? State its practical unit.

Answer 1

Potential difference:

1. Potential difference $V=\frac{W}{Q}$
2. where $W-$Work done and $Q-$Charge
3. The amount of work done to transport a unit charge from one point in the circuit to another is described as the potential difference.

The practical unit of potential difference:

1. Potential difference in the International System of Units (SI) are represented in$joulespercoulomb$ and differences in potential are measured with a voltmeter.
2. $V=\frac{1joule}{1coulomb}=1volt$
3. Its practical unit is$onevolt$.
