Question

A fresh dry cell of 1.5 V and two resistors of 10 kΩ each are connected in series. An analog voltmeter measures a voltage of 0.5 V across each of the resistors. A 1000μF capacitor is fully charged using the same source. The same voltmeter is now used to measure the voltage across it. The initial value of the current and the time in which the voltmeter reading falls to 0.5 V are respectively

(a)  60 μA, 11 s 

(b)  120 μA, 15 s 

(c) 150 μA, 15 s 

(d)  150 μA, 11 s

Answer 1

Correct option  d) 150  μA, 11 s

Explanation:

Let the resistance of the voltmeter be R kΩ
