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.

(b) What charge does the end Q have?
(c) What charge does the cap of the electroscope have?
(d) What charge does the gold leaf have?
(e) Will the leaf diverge or collapse? Give reason.
(f) If the electroscope is now earthed, what charge does the metal rod have?
