Question

. A pure inductor of 20mH is connected to a source of 220 V. find the induction reactance if the frequency of the source is
50 Hz​

Answer 1

Answer:

Inductance of Inductor, L = 20 m H

= 20 x 10-3 H

Supply Voltage, V = 220 V

Frequency, f = 50 Hz

Inductive reactance , XL = 2? f L

= 2 x 3.14 x 50 x 20 x 10^-3

= 6.28 ?

$rms \: value \: of \: current \: \: \: i = \frac{v}{xl}$

$i = \frac{220}{2 \times 3.14 \times 50 \times 20 \times 10^{ - 3} }$

$i =345.4$
