Question

The output voltage of an AC generator is given by Δv =
(170 V) sin (60πt). The generator is connected across a
20.0 - Ω resistor. By inspection, what are the (a) maximum voltage
and (b) frequency? Find the (c) rms voltage across the
resistor, (d) rms current in the resistor, (e) maximum current
in the resistor, (f) power delivered to the resistor, and (g) current
when t = 0.005 0 s. (h) Should the argument of the sine
function be in degrees or radians?
