Determine the charge on the capacitor in the following circuit:

Options

  1. A2 μ C
  2. B60 μ C
  3. C10 μ C
  4. D200 μ C

Correct answer

D. 200 μ C

Step-by-step solution

After a long time capacitor branch will behave like open circuit so circuit will be like, Equivalent resistance is R = 6 + 4 | | 2 + 10   Ω   =   9   Ω and, the current through battery becomes 72 9 = 8   A From the circuit shown, current through 10   Ω   resistor becomes, 4 ( 10 + 2 + 4 ) × 8 = 2   A Potential available for capacitor is = potential drop across 10   Ω ∴     Potential available for capacitor is: 10 × 2 = 20 &#1
