Question

What is the potential difference? Explain. and give its unit with the definition.

Answer 1

Potential difference:

1. The amount of work done in moving a unit charge from one point to another is defined as the potential difference between any two points.
2. Potential difference can be written as $\mathrm{v}=\frac{\mathrm{w}}{\mathrm{Q}}$. Here, $w$ is work done and $Q$ is charge.
3. $\mathrm{Volt}$ is the SI unit of potential difference (V).
4. $1\mathrm{volt}$ is defined as when $1\mathrm{Joule}$ of work is done in moving a charge $1\mathrm{coulomb}$ from one point to another.
