The output voltage of an AC generator is given by v = (1.20 × 10 2 V) sin (30 t ). The generator is connected across a 0.500-H inductor. Find the (a) frequency of the generator, (b) rms voltage across the inductor, (c) inductive reactance, (d) rms current in the inductor, (e) maximum current in the inductor, and (f) average power delivered to the inductor. (g) Find an expression for the instantaneous current. (h) At what time after t = 0 does the instantaneous current first reach 1.00 A (Use the inverse sine function.)
