In this diagram, the PD between A and B is 60 ~V , The PD across 6 F capacitor is

Options

  1. A4 ~V
  2. B10 ~V
  3. C5 ~V
  4. D20 ~V

Correct answer

B. 10 ~V

Step-by-step solution

Let us first calculate equivalent capacitance between A and B . C _ e =1 F (In series combination) Charge on the combination, q = CV =1 60=60 C As 6 F capacitor is in series with all other capacitors, hence, charge on 6 F capacitance is also 60 C , Potential difference across 6 F capacitor V ₁= q C ₁ = 60 6 =10 ~V
