Calculate the value of the capacitive reactance during resonance if the value of the inductor is 5 H and supply frequency is 20 rad/sec.(a) 100 Ω(b) 200 Ω(c) 300 Ω(d) 700 ΩThe question was posed to me in my homework.This interesting question is from Regenerative Braking of DC Shunt Motors in section Braking of DC Motors & Induction Motors of Electric Drives

Answer» CORRECT CHOICE is (a) 100 Ω

To explain I WOULD say: Resonance is DEFINED as the phenomenon in which energy of any element changes from one form to another. During resonance condition Xc=Xl=ΩL=20×5=100 Ω.
