1. An AC generator is connected to a "black box" through a pair of terminals. The box contains an RLC circuit, whose elements and connections we do not know. Measurements outside the box show: v(t) = (75.0 V)sin (wt), and i(t) = (1.20 A)sin (wt + 42°). 2. i(t) a) Does the current lead or lag the source voltage? b) Is the circuit in the box in resonance? Explain. c) Must there be a capacitor in the box? Explain.
