Can anyone help me? I'm really lost on what this is. I solved all the other parts of the problem.
Question: The output voltage of an AC generator is given by Δv = (1.09 ✕ 10^2 V)sin(45𝜋t). The generator is connected across a 0.500 H inductor. Find the following.
(a) frequency of the generator = 22.5 Hz
(b) rms voltage across the inductor = 77.07 V
(c) inductive reactance = 70.7 ohms
(d) rms current in the inductor = 1.09 A
(e) maximum current in the inductor = 1.54 A
(f) average power delivered to the inductor = 0 W
(g) Find an expression for the instantaneous current. = 1.54sin(45𝜋t-𝜋/2)
What I need help with: (h) At what time after t = 0 does the instantaneous current first reach 1.00 A? (Use the inverse sine function.)
