3.2 Potential and Potential Difference in a Circuit

Series Circuit

The sum of the potential difference across individual resistor in between 2 points in a series circuit is equal to the potential difference across the two points.

V = V1 + V2

Example

Parallel Circuit

The potential difference across all resistors in a parallel circuit is the same.

V = V1 = V2

Example
