$ω = 2 π f = 2 π * 50 = 100 π$

$X_{L} = w L = 100 π * 100 * 1 0^{- 3}$

$X_{C} = \frac{1}{w C} = \frac{1}{100 π} * 100 * 1 0^{- 6} = \frac{100}{π}$

$z = 10.0086 Ω$

$l = \frac{v}{z} = \frac{220}{10.008} = 22 A$

Vishal Baghel

R = $2 Ω$

L = 2 mH

E = 9V

$i = \frac{ε}{2 R} = \frac{9 v}{4 Ω} = 2.25 A$

Just after the switch ‘S’ is closed, the inductor acts as open circuit.
