An inductor of 30 mH is connected to a 220 V, 100 Hz ac source. The inductive reactance is

$10.58\ \Omega$

$12.64\ \Omega$

$18.85\ \Omega$

$22.67\ \Omega$

Answer

$18.85\ \Omega$

Explanation

: Here, , $L = 30mH = 30 \times 10^{- 3}H$

$V_{rms} = 220V,\upsilon = 100Hz$

Inductive reactance,

$X_{L} = 2\pi\upsilon L = 2 \times 3.14 \times 100 \times 30 \times 10^{- 3} = 18.85\Omega$
