Electrostatics Question 79

Question: An air capacitor of capacity C=10μF is connected to a constant voltage battery of12V . Now the space between the plates is filled with a liquid of dielectric constant 5. The charge that flows now from battery to the capacitor is [MP PMT 1997]

Options:

A) 120μC

B) 699μC

C) 480μC

D) 24μC

Show Answer

Answer:

Correct Answer: C

Solution:

Initially charge on the capacitor Q=10×12=120μC

Finally charge on the capacitor Q=(5×10)×12=600μC

So charge supplied by the battery later =QQ=480μC
