➡ Given:

✏ Induction of a coil = 0.25H

✏ A.C. frequency = 50Hz

➡ To Find:

✏ Inductive reactance = ?

➡ Calculation:

$\implies \rm \: X{ \tiny{L}} = \omega \times L \\ \\ \implies \rm \: X{ \tiny{L}} = (2\pi{f}) \times L\\ \\ \therefore \rm \: X{ \tiny{L}} = 2\pi \times 50 \times 0.25 \\ \\ \therefore \: \underline{ \boxed{ \bold{ \rm{ \pink{X{ \tiny{L}} =78.5 \: \Omega }}}}}$
