The path that an electrical current flows. Electricity Notes 6 - Circuits Source of electric current (battery or wall outlet) Load, device that uses the electric current. Electric Circuit – _______________________________________ All electrical circuits have 4 parts: 1.____________________________________________________ 2.____________________________________________________ ____________________________________________________ 3.____________________________________________________ 4.____________________________________________________ (Light bulb, motor, toaster etc.) Wires, used for connecting the circuit together. Switch, turns the system on and off.
Open/Closed Circuits • Open Circuit – ________________________________ ____________________________________________ • Closed Circuit – _______________________________ • ____________________________________________ Electric current can not flow through an open circuit. (switch off) No connection. Electric current can flow through circuit. (Switch on) Connection.
