A capacitor of capacitance is charged to a potential difference of with a battery. The battery is then removed and in its place another capacitor of capacitance is introduced and the circuit is closed. The potential difference attained by each of the capacitors in is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
When two capacitors are connected in series then their equivalent capacitance is, Ceq=C1C2C1+C2=4×84+8=83 μF Q=CeqV=83×6=16 μC Now V1=QC1=164=4 V & V2=QC2=168=2 V ∴ ∆V=4-2=2 V
