उत्तर
A: Ammeter - It measures the current flowing through the circuit.
B: Cell - It acts as a source of direct current for the circuit.
C: Key - It is used to put the current on and off in the circuit.
D: Load - It is an appliance connected in a circuit. It may just be a resistance (e.g., bulb) or a combination of different electrical components.
E: Voltmeter - It is used to measure the potential difference between two points of a circuit.
F: Rheostat - It is used to control the current in the circuit.
