A baterry consits of 2 or more cells 1 of 10 switch enables the current to be switched on or off in a circuit 2 of 10 indicator it emits light to signal that a current has passed through it 3 of 10 diode stops the current flowing in a particular direction 4 of 10 ammeter it measures electric current 5 of 10 fixed resistor it limits the current in a circuit 6 of 10 variable resistor it allows the current to be varied 7 of 10 fuse it is designed to melt or break a circuit when the current flowing exceeds a certain amount 8 of 10 heater it transfers the electric current to heat its sorroundings 9 of 10 voltmeter measures the potential difference between 2 points in a circuit 10 of 10
