JEE Main 2013 Physics question
In a series L − C − R circuit, Farad, Henry and R = 100Ohm, when a constant D.C. voltage E is applied to the circuit, the capacitor acquires a charge C. The D.C. source is replaced by a sinusoidal voltage source in which the peak voltage is equal to the constant D.C. voltage E. At resonance the peak value of the charge acquired by the capacitor will be :
