question_answer
In a series L-C-R circuit, \[\text{C}=\text{1}{{0}^{-11}}\] Farad, \[\text{L}=\text{1}{{0}^{-5}}\] Henry and \[\text{R}=100\] Ohm, when a constant D.C. voltage E is applied to the circuit, the capacitor acquires a charge \[\text{1}{{\text{0}}^{-9}}\operatorname{C}.\] The D.C. source is replaced by a sinusoidal voltage source in which the peak voltage \[{{\operatorname{E}}_{0}}\] is equal to the constant D.C voltage E. At resonance the peak value of the charge acquired by the capacitor will be: [JEE ONLINE 22-04-2013]
