Electricity
Electrical power flows from the power source to a load device and then back to the source of power. The electrical circuit should contain a device to open or close the circuit, such as a switch or relay, and a protective device (in case of an overload), such as a circuit breaker or a fusible link. Electrical circuits can be set up as series circuits, parallel circuits, or series/parallel circuits. The circuits in this vehicle are normally parallel circuits.
