An ac generator produces emf according to E(t) = Vm sin(ωdt - π/4). The current in the circuit attached to the generator is given by i(t) = Im sin(ωdt + π/4). (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 - type "0", an inductor - type "1", or a resistor - type "2"? (d) What is the value of the capacitance, inductance, or resistance, as the case may be? Express your answers in terms of Vm, Im, ωd, and π.
