On substituting this value of w in the

resistance at resonance is given by R ' = L / RC . The effective resistance at

resonance is therefore inversely proportional to the resistance of the inductance .

On substituting this value of w in the

**expression**for R ' , it is seen that the effectiveresistance at resonance is given by R ' = L / RC . The effective resistance at

resonance is therefore inversely proportional to the resistance of the inductance .
