An ac generator has emf ε = εmsin(ωdt − π/4), where εm = 42.0 V and ωd = 346 rad/s. The current produced in a connected circuit is i(t) = Isin(ωdt − 3π/4), where I = 532 mA. At what time after t = 0 does (a) the generator emf first reach 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? (a) Number Units (b) Number Units (c) (d) Number Units
