Question

A 1 µF capacitor is connected in the circuit shown below. The e.m.f. of the cell is 3 volts and internal resistance is 0.5 ohms. The resistors R₁ and R₂ have values 4 ohms and 1 ohm respectively. The charge on the capacitor in steady state must be :

(A) 2 μC 

(B) 1 μC 

(C) 1.33 μC 

(D) zero

Answer 1

Correct option (A) 2 μC 

Explanation: 

In steady state no current flows through capacitor. The potential difference across capacitor and resistor of resistance R₂ is same
