Electrostatics Question 628
Question: All six capacitors shown are identical, Each can withstand maximum 200 volts between its terminals. The maximum voltage that can be safely applied between A and B is [MP PMT 2004]
Options:
A) 1200 V
B) 400 V
C) 800 V
D) 200 V
Show Answer
Answer:
Correct Answer: B
Solution:
Given circuit can be reduced as follows (C = capacitance of each capacitor).
the capacitor 3C, 3C can withstand maximum 200 V.
So maximum voltage that can be applied across A and B is equally shared. Hence maximum voltage applied across A and B is equally shared.
Hence max. voltage applied across A and B will be (200 + 200) = 400 volts.
