What is the rms current in a 200 mH inductor attached to a 120 V rms, 60.0 Hz source?
A) 600 A
B) 12.0 A
C) 1.59 A
D) 100 A
E) 1.00 A

We can use the formula for the rms current in an inductor given by:

Irms = Vrms / Xl

where Xl is the inductive reactance given by Xl = 2πfL, where f is the frequency and L is the inductance.

Plugging in the given values, we get:

Xl = 2π(60.0 Hz)(0.200 H) = 75.4 Ω

Irms = 120 V / 75.4 Ω = 1.59 A

Therefore, the best choice is C, with an rms current of 1.59 A.
