Q. In a purely inductive $AC$ circuit, $L=30.0\, mH$ and the rms voltage is $150\, V$, frequency $v=50\, Hz$. The inductive reactance is

Alternating Current

Solution:

The inductive reactance,
$X_{L}=2 \pi v L=2 \times 3.14 \times\left(50\, s ^{-1}\right) \times\left(30.0 \times 10^{-3} H \right)$
$=9.42\, \Omega$
