A) 0.366 A
B) 0.379 A
C) 0.398 A
D) 0.413 A

The reactance of an inductor can be calculated using the formula Xl = 2πfL, where Xl is the inductive reactance, f is the frequency, and L is the inductance.

Plugging in the given values, we get Xl = 2π(60)(0.8) = 301.59 Ω.

Using Ohm's law, we can find the current through the circuit: I = V/Xl = 120/301.59 = 0.398 A.

Therefore, the answer is C.

An Inductor Has an Inductance of 0
