An ac generator has emf ε = εmsin(ωdt - π/4), where εm = 34.5 V and ωd = 307 rad/s. The current produced in a connected circuit is i(t) = I sin(ωdt - 3π/4), where I = 507 mA. At what time after t = 0 does (a) the generator emf first reach a maximum and (b) 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?
