Electrostatics Question 633

Question: Three capacitors of capacitance 1 mF, 2 mF and 3 mF are connected in series and a potential difference of 11 V is applied across the combination. Then, the potential difference across the plates of 1 mF capacitor is [DCE 2003]

Options:

A) 2 V

B) 4 V

C) 1 V

D) 6 V

Show Answer

Answer:

Correct Answer: D

Solution:

Equivalent capacitance 1Ceq=11+12+13

therefore Ceq=611μF

Charge supplied from battery Q=611×11=6μC

Hence potential difference across 1mF capacitor =61=6V
