If inductance of an inductor L = 15 mH and frequency f = 80 KHz. Find its Inductive Reactance?
Given,
Inductance (l) = 15 mH
Frequency (f) = 80 KH
we have;
Inductive Reactance = 2 pi.f.L
= 2 x 3.14 x 80 x 103x 15 x 10-6
= 7.536 ohm
What is phasor? How can one represent alternating current with help of phasor? Why is rms value of AC is more useful (meaningful) in daily life than mean value? Explain.
