Calculate the amount of charge on capacitor of 4 μF . The internal resistance of battery is 1 Ω :

Options

  1. A4   μC
  2. B8   μC
  3. C16   μC
  4. Dzero

Correct answer

B. 8   μC

Step-by-step solution

Using i = 5 4 + 1 = 1   A ∴ V A B = i × 4 = 4   V   ∴ V A C = V C B = 2 Volt ∴ q on 4 μ F = C V A C = 8 μ C
