(a) frequency of the generator?=____ Hz
(b) rms voltage across the inductor?=____
V
(c) inductive reactance?=____
ohms
(d) rms current in the inductor?=____
A

A
(f) average power delivered to the
inductor?=____ W
(g) Find an expression for the instantaneous
current. (Use the following as necessary: t.)
" i=_________ "
(h) At what time after t = 0 does the instantaneous current
first reach 1.00 A? (Use the inverse sine function.)?=_____
