NAME DATE PERIOD SERIES AND PARALLEL CIRCUITS ELECTRIC CIRCUITS An electric circuit provides a complete, closed path for an electric current. Electricity can only flow through a closed circuit; it cannot flow through an open circuit. Every circuit MUST have the following parts: 1. energy source: battery, electric generator, etc. 2. load or resistance: device that uses the electric energy 3. wires 4. switch: opens and closes the circuit SERIES CIRCUIT All parts are connected one after another. . If one part fails to operate properly, the current 3 can not flow to the other parts. PARALLEL CIRCUIT . Different parts of circuit are on different branches. If one part does not operate properly, current can still flow through the others.
