PHYS208 Fundamentals of Physics II

Answer for Ch. 33, 55P

The resonant frequency of the circuit is 1000 rad/s. Thus the inductive reactance is 1000 ohm. However at resonance the impedance of the circuit is just the resistance 10 ohm, with a resulting current at resonance of (10 V)/(10 ohm) = 1.0 A. The resulting voltage across the inductor (and capacitor, pi out of phase) is (1.0 A)(1000 ohm) = 1000 V!
