Question: The voltage V, in volts, produced by an ac generator at time t, in seconds, is V(t) = 220 sin(120t) (a) What is the amplitude?

The voltage V, in volts, produced by an ac generator at time t, in seconds, is

V(t) = 220 sin(120πt)

(a) What is the amplitude? What is the period?

(b) Graph V over two periods, beginning at t = 0.

(c) If a resistance of R = 10 ohms is present, what is the current I?

(d) What is the amplitude and period of the current I ?

(e) Graph I over two periods, beginning at t = 0.
