Question

The reactance  ) of an inductor is 10 Ω at 1 kHz. The inductance of this inductor is
A) 1.00 mH. 
B) 1.59 mH. 
C) 2.06 mH. 
D) 2.86 mH. 
E) 3.45 mH.

Quizplus · Accepted Answer

Reactance of an inductor, XL = 2πfL

Given, XL = 10Ω and f = 1kHz
10 = 2π × 1 × L
L = 10 / (2π)
L = 1.59 mH.

Therefore, the answer is B, 1.59 mH.

The Reactance ) of an Inductor Is 10 Ω
