Why does your home have a circuit breaker or fuse box?

Circuit Symbols Wire (conductor) Light bulb Closed switch BatteryOpen switch

Circuit Types Series Circuit Current has only one loop to flow through. Ex. Flashlight, holiday lights Parallel Circuit Contains two or more branches for current to flow through. Ex. Homes, autos.

Circuit Types Series CircuitParallel Circuit

Complex Circuit A circuit composed of both series and parallel circuits.

Electrical energy enters your home at the circuit breaker or fuse box and branches out to appliances, wall sockets, and lights. Circuit breaker – small piece of metal that bends when it gets hot, opening the circuit and stopping current flow Electric fuse – small piece of metal that melts if current becomes too high, opening the circuit
