Two capacitors of capacitance C1 and C2 are connected in parallel.
If the charge ‘O’ is given to the assembly, it gets shared. The ratio of the charge on the capacitor C1 to the charge on capacitor C2 is given by:
- A
C1/C2
- B
C2/C1
- C
(C12) / (C22)
- D
(C22) / (C12)
- E
(C22) / 2C2
The correct option is A
This is correct because the charge on each capacitor in a parallel connection is directly proportional to its capacitance.
This is incorrect because it reverses the ratio of the capacitances.
This is incorrect because it incorrectly uses the square of the capacitances, which is not applicable in calculating charge ratios.
This is incorrect because it reverses the ratio and incorrectly uses the square of the capacitances.
This is incorrect because it introduces an irrelevant factor of 2, which is not part of the correct ratio calculation.
