An inductor is connected to a 24V, 50Hz mains supply. If the current through the inductor is 1.5A, calculate the inductance of the inductor ((pi = frac{22}{7}))
-
A.
8.0 x 102H -
B.
7.5 x 10oH -
C.
1.6 x 10oH -
D.
5.1 x 10-2H
Correct Answer: Option D
Explanation
(X_L = frac{V}{I} = frac{24}{1.5} = 16Omega)
L = (frac{XL}{2 pi f} = frac{16}{2 pi 50})
= 0.05H
