Two capacitors C 1 and C 2 are charged to 120 V and 200 V respectively. It is found that by connecting them together the potential on each one can be made zero. Then:

Options

  1. A3 C 1 + 5 C 2 = 0
  2. B9 C 1 = 4 C 2
  3. C5 C 1 = 3 C 2
  4. D3 C 1 = 5 C 2

Correct answer

D. 3 C 1 = 5 C 2

Step-by-step solution

For potential to be made zero, after connection 120 C 1 = 200 C 2 ⇒ 3 C 1 = 5 C 2
