==Key Stage 4==
===Meaning===
A '''circuit''' is a loop of [[wire]] that [[electricity]] flows around.
===About Circuits===
: [[Circuit]]s can have [[component]]s in [[Series Circuit|series]] or [[Parallel Circuit|parallel]].
: [[Component]]s in [[Parallel Circuit|parallel]] in a [[circuit]] have the same [[Potential Difference]] across them but share the [[Electrical Current|current]].
: [[Component]]s in [[Series Circuit|series]] in a [[circuit]] have the same [[Electrical Current|Current]] through them but share the [[Potential Difference|potential difference]].
