Explanation of Series R-L-C Resonance circuit: A series circuit containing resistance, inductance and capacitance, is said to be resonant when the circuit power factor is unity,(XL = XC) i.e. applied voltage and current are in phase. This condition is termed as series resonance. 


OR


In a series RLC circuit there becomes a frequency point were the inductive reactance of the inductor becomes equal in value to the capacitive reactance of the capacitor. In other words, XL = XC. The point at which this occurs is called the Resonant Frequency point, ( ƒr ) of the circuit, and as we are analyzing a series RLC circuit this resonance frequency produces a Series Resonance.
