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. 1. At t=1.25 us, the current is maximum. 2. At t=2.50 us, the charge on the lower plate has its maximum positive value. 3. At t=1.25 us, half the energy is stored in the capacitor, half in the inductor. 4. At t=5.00 us, the energy is completely stored in the capacitor. 5. At t=1.25 us, the charge on the lower plate has its maximum positive value. 6. At t=2.50 us, the current is zero.

For an RLC circuit in the limit of very high frequency, what is the effective behavior of the capacitor and the inductor in the circuit? O A.
