An AC generator has a sinusoidal EMF with a maximum value of 28.0 V and a freque

Question

An AC generator has a sinusoidal EMF with a maximum value of 28.0 V  and a frequency of 60.0 Hz; the generator is connected to an inductor of inductance 11.50 H.  The resistance in the circuit is small enough to ignore.

(a) What is the maximum value of the current in this AC circuit?
     A

(b) At the instant of time for which the current in this circuit is a maximum, what is the EMF of the generator?
     V

(c) At the instant of time for which the EMF of the generator is %u22129.8000 V and increasing in absolute value, what is the current in the circuit?
     A

(d) At the same instant of time as in part (c), what is the power output of the generator?
     W

Explanation / Answer

a)28%u221A2
