Three capacitors each of capacitance C and of breakdown voltage V are joined in series. The capacitance and breakdown voltage of the combination will be

Options

  1. AC 3 , V 3
  2. B3 C , V 3
  3. CC 3 , 3 ~V
  4. D3 C , 3 ~V

Correct answer

C. C 3 , 3 ~V

Step-by-step solution

In series arrangement charge on each plate of each capacitor has same magnitude. The potential difference is distributed inversely in the ratio of capacitors ie, V = V ₁+ V ₂+ V ₃ Here, V=3 V The equivalent capacitance C _s is given by aligned & 1 C_s = 1 C₁ + 1 C₂ + 1 C₃ + & C_s= C 3 aligned
