Question

The potential difference between the points P and Q in the adjoining circuit will be-
                                

Options

A.
B.
C.
D.

Solution


C1 and C2 are in series, charge on each will remain same.
(VP − 0) . C1 = (E − VP) C2
VP =
C3 & C4  are in series, charge on each will remain same,
(VQ − 0) . C3 = (E − VQ) . C4 
VQ =
Hence  VP − VQ  =
