The potential difference (voltage) of the supply is shared between components in a series circuit.

Also known as "Kirchoff's Voltage Law" or "KVL".

Solving Circuit Diagrams - Worksheet with Answers

Current is the same everywhere in a series circuit.

Current in series circuits

Current is divided when branches of a parallel circuit split.

Current is combined when branches of a parallel circuit join.

The total current flowing into a junction equals the total current flowing out of the junction.

This is also known as "Kirchoff's Current Law" or "KCL".

Current parallel circuits

The potential difference (voltage) across each branch of a parallel circuit is the same.
