Given : reactance of the inductor of 50
frequency 25/π kHz
To Find : inductance of the inductor
Solution:
XL = reactance of the inductor = 50
XL = ωL = 2πfL
f = Frequency in Hz 25/π khz = 25/π x 1000 Hz
L = inductance
50 = 2π ( 25/π x 1000) * L
=> 1 = 1000 * L
=> L = 1/1000
=> L = 1 mH
inductance of the inductor = 1 mH
