Question

In the adjoining circuit diagram, E = 5 V , r = 1 Ω , R 2 = 4 Ω , R 1 = R 3 = 1 Ω and C = 3 mF . Then the numerical value of the charge on each plate of the capacitor is, 24 μC, 12 μC, 6 μC, 3 μC

MARKS App · Accepted Answer

Current through resistors R 1 and R 3 in steady state is zero. Therefore current through R 2 is i 2 = E R 2 + r = 5 4 + 1 = 1 A Therefore charge on capacitor is q = C i 2 R 2 2 = 6 μC
