Question

The frequency of oscillation of the LC circuit in the figure is 200 kHz. At time t=0 the upper capacitor plate has its maximum positive charge. Select True or False for all statements. At t 2.50 us, the current is zero. At t-5.00 us, the current is maximum. At t 1.25 us, half the energy is stored in the capacitor, half in the inductor. At t-1.25 us, the charge on the lower plate has its maximum positive value. At t 2.50 Hs, the energy is completely stored in the inductor. At't 2.50 us, the charge on the lower plate has its maximum positive value. Submit Answer Tries 0/12 Post Discussion Send Feedback
