A capacitor having capacitance \[C\] is charged to a voltage \[V\]. It is then removed and connected in parallel with another identical capacitor which is uncharged. The new charge on each capacitor is now [MP PET 1990]
A) CV
B) CV / 2
C) 2 CV
D) CV / 4
Correct Answer:
B
Solution :
Charge flows to second capacitor until the potential is same i.e. V/2. So new charge = CV/ 2
