Electrons can only flow along one path, and MUST go through each component before getting to the next one.

4. A Parallel Circuit A Source Battery A Load 3 Lamps A Conductor Wire
A Control Switch
Two or more components are connected so that current can flow to one of them WITHOUT going through another

5. A Series-Parallel Circuit
A combination of components both in Series and in Parallel
