Problem
In a series L-C-R circuit, C=10−11 Farad, L=10−5 Henry and R=100 Ohm, when a constant D.C. voltage E is applied to the circuit, the capacitor acquires a charge 10−9 C. The D.C. source is replaced by a sinusoidal voltage source in which the peak voltage E0 is equal to the constant D.C. voltage E . At resonance the peak value of the charge acquired by the capacitor will be :
(1) 10−15 C
(2) 10−6 C
(3) 10−10 C
(4) 10−8 C
