lamp

Back

Lights up when current flows through it

Front

fuse

Back

Breaks a circuit if too much current flows through it by the metal wire melting

Front

open switch

Back

Creates a break in the circuit so that current cannot flow

Front

diode

Back

Allows current to flow through it in one direction only

Front

voltmeter

Back

Measures potential difference across a component in volts

Front

cell

Back

Source of potential difference in a circuit

Front

resistor

Back

Has a designed resistance to electric current passing through it

Front

thermistor

Back

A resistor which reduces in resistance when heated

Front

LED

Back

Diode that emits light when a voltage is applied

Front

closed switch

Back
