An ac generator has emf & = &m sin(ωdt - π/4), where &m = 30.0 V and ωd = 350 rad/s. The current produced in a connected circuit is i(t) = I sin(ωt 3π/4), where I = 620 mA. At what time after t = 0 does
(a) The generator emf first reaches a maximum
(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? Justify your answer.
(d) What is the value of the capacitance, inductance, or resistance, as the case may be?
