Class 12 NEET Physics Electrostatics Questions Part 1

Charge on first capacitor =q1=C1V
Charge on second capacitor =q2=0
When they are connected, in parallel the total charge q=q1+q2
∴q=C1V
and capacitance, C=C1+C2
Let V′ be the common potential difference across each capacitor, then q=CV′
V′=

q

C

=

C1

C1+C2
