The wireless power transfer system is outlined in Figure VI.2. An AC supply generates a current through the primary coil, creating a varying magnetic field. This field induces a current in the secondary coil, which is connected to a resistance (the lightbulb) and a capacitor that sets the resonance frequency of the secondary circuit to match the frequency of the primary circuit.
What are the rms and peak currents for a 60 W bulb? (The rms voltage is the usual 120 V.)
A. 0.71 A, 0.71 A
B. 0.71 A, 0.50 A
C. 0.50 A, 0.71 A
D. 0.50 A, 0.50 A
