Open in App

Solution

(i) Key
It is used to switch the current on or off in the circuit.

(ii) Cell
It acts as a source of direct current for the circuit.

(iii) Rheostat
It is used to control the current in the circuit. It is basically a variable resistence.

(iv) Ammeter
It is used to measure the current flowing through the circuit.

(v) Voltmeter
It is used to measure the potential difference between two points of a circuit.
