allowing or stopping current
from flowing
Resistor
Restricts the flow of current
Variable resistor
Precisely controls how much
current can pass through
Diode
A device which only allows
current to flow in one
direction
LDR
Light dependent resistor
which converts brightness
(light) to resistance
LED
Light emitting diode,
converting electrical energy
into light
Thermistor
Converts temperature (heat)
to resistance
Motor
Converts electrical energy
into kinetic (movement)
energy
Ammeter
Measures the current within
the circuit
Voltmeter
Measures the voltage within
the circuit
Fuse
A safety device which will
‘blow’ if the current passing
it exceeds a given limit
Buzzer
Converts electrical energy
into sound energy
