(2 or more cells in series) Electrical symbols Wire Cell Supply energy to e-. Battery or Power pack (2 or more cells in series)

Electrical symbols: battery and cell 9V Cell 1.5V Battery or Power pack 9V = 1.5V + 1.5V + 1.5V + 1.5V + 1.5V + 1.5V

Electrical Symbols Wire Conduct electricity around the circuit. Wires crossing (not joined) Wires crossing (joined)

Convert electrical energy into light and heat energy. Electrical symbols Lamp (indicator) Lamp (lighting) Convert electrical energy into light and heat energy. Switch (close) On Switch (open) Off

Convert electrical energy into heat energy. Electrical symbols Resistor Convert electrical energy into heat energy. Rheostat (variable resistor) Variable resistor

Measures the current in a circuit. Electrical symbols Voltmeter Measures the potential difference (voltage) between 2 points in a circuit . Multimeter Ammeter Measures the current in a circuit.

Electrical symbols Fuse A diode or a light-emitting diode (LED) Wire of low melting point that breaks a circuit if the current exceeds a certain value. Ordinary diode LED A diode allows the current to flow in one direction but not in the opposite direction. LED also glows if it is conducting current.
