PhysicsElectricityGCSENone Created by: Luuuuucy123Created on: 13-01-21 11:44 Voltmeter Used to measure potential different (voltage) between two points in a circuit 1 of 14 Lamp A component that transforms electrical energy into light 2 of 14 Cell Supplies electrical energy. Larger terminal is positive. Normally 1.5V 3 of 14 Motor A component that turns the electrical store into kinetic store. 4 of 14 Ammeter Used to measure current in a circuit. 5 of 14 Open Switch An on-off switch allows current to flow only when it is in the closed (on) position. 6 of 14 Battery Supplies electrical energy. Made up of multiple cells. 7 of 14 Resistor Restricts the flow of current in a circuit 8 of 14 Light-dependent resister (LDR) A component whose resistance is relate to the amount of light falling on it. 9 of 14 Light-emitting diode (LED) A component that transforms electrical energy into light. 10 of 14 Variable resistor A component used to vary and control the current in a circuit. 11 of 14 Diode A component that allows current to flow in one direction. 12 of 14 Thermistor A component whose resistance is related to temperature 13 of 14 Fuse A safety device that will break the circuit and stop current flowing if the current flowing through it exceeds a specific value 14 of 14
