An ac generator produces emf = m sin(ωd t - π/4), where m = 31.8 V and ωd = 363 rad/s. The current in the circuit attached to the generator is given by i(t) = I sin(ωd t + π/4), where I = 626 mA. (a) At what time after t = 0 does the generator emf first reach a maximum? (b) At what time after t = 0 does the current first reach a maximum? (c) The circuit contains a single element other than the generator. Is it a capacitor, an inductor, or a resistor? (d) What is the value of the capacitance, inductance, or resistance, as the case may be?
