Electrostatics Question 276

Question: A finite ladder is constructed by connecting several sections of 2μF, 4μF capacitor combinations. It is terminated by a capacitor of capacitance C. What value should be chosen for C such that the equivalent capacitance of the ladder between the points A and B becomes independent of the number of sections in between [MP PMT 1999; KCET (Engg./Med.) 1999]

Options:

A) Zero

B) 25CV26

C) 3CV22

D) 9CV22

Show Answer

Answer:

Correct Answer: C

Solution:

Total charge =(2C)(2V)+(C)(V)=3CV

Common potential =3CV3C=V

Energy =12(3C)(V)2=32CV2
