Electrostatics Question 554

Question: Four capacitors are shown with their respective capacities and the P.D. applied. The charge and the P.D. across the 4μF capacitor will be

Options:

A) 600μC; 150 volts

B) 300μC; 75 volts

C) 800μC; 200 volts

D) 580μC; 145 volts

Show Answer

Answer:

Correct Answer: D

Solution:

Total capacitance 1C=120+18+112 t

herefore C=12031μF Total charge Q=CV=12031×300=1161μC

Charge, through 4 mF condenser =11612=580μC

and potential difference across it =5804=145V
