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) T.
he capacitor 3C, 3C can with stand maximum 200 V.
So maximum voltage that can be applied across A and B equally shared. Hence maximum voltage applied cross A and B be equally shared.
Hence max. voltage applied across A and B will be (200 + 200) = 400 volt.
