|
Cell Provides energy to push current around a circuit. |
|
|
Battery Two or more cells in series. |
|
|
Switch Breaks or rejoins the circuit, turning the current on or off. This switch is open so no current flows. |
|
|
Lamp Light shown as the current flows. |
|
|
Fixed resistor size affects size of current |
|
|
Ammeter Measures current |
|
|
Voltmeter Measures voltage |
|
|
Variable Resistor Allows size of current to be varied |
|
|
Fuse Melts when current becomes too high |
|
|
Heater Transfer electrical energy to heat |
|
|
Diode only allows current to flow in one direction |
|
|
Light Emitting Diode LED Emits light as current flows can be used as indicator of switched on current |
|
|
Light Depending Resistor LDR Emits lots of light when LI is low and little when LI is high |
|
|
Thermistor Emits lots of heat when cold and little when hot |
|
|
Motor Electrical energy to Kinetic |
|
|
Generator Kinetic energy to Electrical |
|
|
Loudspeaker Electrical energy to Sound |
|
|
Microphone Sound energy to Electrical |
|
|
Earth Wire Prevents shocks in circuits when fault occurs |
