Question

A 10 μF capacitor and a 20μ F capacitor are connected in series across 200 V supply line. The charged capacitors are then disconnected from the line and reconnected with their positive plates together and negative plates together and no external voltage is applied. What is the potential difference across each capacitor?

  1. 800 over 9 straight V
  2. 800 over 3 straight V
  3. 400V
  4. 200V

The correct answer is: 800 over 9 straight V
