Learn how electric circuits work and how to measure current and potential difference with this guide for KS3 physics students aged 11-14 from BBC Bitesize.

Series and Parallel Circuit Series and parallel circuits are two fundamental configurations in electrical circuits, each with distinct characteristics that affect how electricity flows through them.

Potential difference in parallel circuits Since energy has to be conserved, the energy transferred around the circuit by the electrons is the same whichever path the electrons follow.
