What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit in which the components are connected alongside each other, so the current can split and flow through multiple paths.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which the components are connected end-to-end, so the current flows through each component in turn.
