Question

Two capacitators having capacitances C1 and C2 are charged with 120 V and 200 V batteries respectively. When they are connected in parallel now, it is found that the potential on each one of them is zero. Then:
  1. 9C1=5C2
  2. 3C1=5C2
  3. 8C1=5C2
  4. 5C1=3C2

A
8C1=5C2
B
9C1=5C2
C
5C1=3C2
D
3C1=5C2
Solution
Verified by Toppr

On capacitor C1 charge Q1=C1V1=120C1
On capacitor C2 charge Q2=C2V2=200C2
When connected in parallel, potential across each capacitor is zero. Thus charge across each capacitor is zero.
Hence charges on capacitors must be equal such that when connected in opposite polarities, net charge becomes zero.
120C1=200C2
3C1=5C2
