Electrostatics Question 577

Question: Three capacitors of 2.0, 3.0 and 6.0 μF are connected in series to a 10V source. The charge on the 3.0μF capacitor is [MP PMT 1996; RPMT 1999; Pb. PMT 2001]

Options:

A) 5μC

B) 10μC

C) 12μC

D) 15μC

Show Answer

Answer:

Correct Answer: B

Solution:

Net capacitance =1(12+13+16)=1μF

Total charge =CV=1μF×10V=10μC

Total charge on every capacitor in series system is same.

So charge on 3 mF is 10 mC.
