What is impedance at resonance?(a) maximum(b) minimum(c) zero(d) cannot be determinedI got this question by my school teacher while I was bunking the class.My query is from Alternating Current in a Capacitive Circuit in chapter Single Phase Series Circuits of Basic Electrical Engineering

Answer» RIGHT answer is (b) minimum

The EXPLANATION is: At resonance, XL=XC

Z^2=R^2+(XL-XC)^2

Z=RSo Z is minimum at resonance.
