calculate the inductance of an inductor whose reactance is one ohm at 50 Hz.
-
A.
2.00 x 10-2H
-
B.
6.36 x 10-2H
-
C.
3.18 x 10-3H
-
D.
4.55 x 10-2H
Correct Answer: Option C
Explanation
The inductive reactance (X\(_L\)) of an inductor is given by the formula:
Given: X\(_L\) = 1\(\Omega\), f = 50Hz
X\(_L\) = 2πfL
L = \(\frac{1}{2πf}\) = \(\frac{1}{2π \times50}\) = \(\frac{1}{100\pi}\) = 3.183 x 10\(^{-3}\)H
