Capacitors in DC Circuits & RC

In the given circuit diagram, in the steady state the current through the battery and the charge on the capacitor respectively are

Figure

Show answer and solution

Answer: (c)

  1. In steady state no current flows in the capacitor branch, so only 1 Ω1\ \Omega, 2 Ω2\ \Omega, 3 Ω3\ \Omega (in parallel) carry current.
  2. 1R=1+12+13=116⇒R=611 Ω\dfrac{1}{R} = 1 + \dfrac{1}{2} + \dfrac{1}{3} = \dfrac{11}{6} \Rightarrow R = \dfrac{6}{11}\ \Omega
  3. I=66/11=11 AI = \dfrac{6}{6/11} = 11\text{ A}
  4. No current through 4 Ω4\ \Omega, so the capacitor gets the full 6 V: Q=0.5×6=3 μCQ = 0.5\times6 = 3\ \mu\text{C}.
  5. So the answer is (c) 11 A and 3 μC3\ \mu\text{C}.
