Hope this answer help you

Answer 2

Series Resonance Frequency

Electrical resonance occurs in an AC circuit when the effects of the two reactances, which are opposite and equal, cancel each other out as XL = XC. ... So the total impedance of the series circuit becomes just the value of the resistance and therefore: Z = R.
