GO An ac generator produces emf ℰ = ℰ m sin( ω d t – π /4), where ℰ m = 30.0 V and ω d = 350rad/s. The current in the circuit attached to the generator is i ( t ) = I sin( ω d t + π /4), where t = 620 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? Justify your answer, (d) What is the value of the capacitance, inductance, or resistance, as the case may be?
