An AC source operating at 57 Hz with a maximum voltage of 170 V is connected in series with a resistor (R = 1.2 k(2) and an inductor (L = 2.0 H). (a) What is the maximum value of the current in the circuit? A (b) What are the maximum values of the potential difference across the resistor and the inductor? AVR,max V AVL, max= (c) When the current is at a maximum, what are the magnitudes of the potential differences across the resistor, the inductor, and the AC source? AVR = V AV, = AV source (d) When the current is zero, what are the magnitudes of the potential difference across the resistor, the inductor, and the AC source? AVR = V
