1. Any arrangement of components that allows an electrical current to flow Basic Electrical Circuits

2. A Basic Circuit There is only one path for the electrons to flow Battery A Source Battery Lamp A LoadLamp Wire A ConductorWire SwitchA Control Switch

3. A Series Circuit Electrons can only flow along one path, and MUST go through each component before getting to the next one. Battery A Source Battery 2 Lamps A Load2 Lamps Wire A ConductorWire Switch A Control Switch

4. A Parallel Circuit Two or more components are connected so that current can flow to one of them WITHOUT going through another A Source Battery A Load3 Lamps A ConductorWire A Control Switch

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