Q. An inductance 1 H is connected in series with an AC source of 220 V and 50 Hz. The inductive reactance (in ohm) is
A) $2\ \pi$
B) $50\ \pi$
C) $100\ \pi$
D) $1000\ \pi$
Explanation
(c) Inductive reactance${\ X}_{L} = \omega L$
$\ = 2\pi vL$
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ = 2\pi \times 50 \times 1$
$= 100\pi$
