Properties of Series Resonance
1.Impedance Z = R
2.Voltage across L and C are equal (i.e.) VL= VC
3.Current in the resonance circuit is maximum.
4.It magnifies voltage.
5.It also called as acceptor circuit.
6.Power factor is unity.(i.e.) cos =1
Resonance:
Inductive reactance increases as the frequency is increased, but capacitive reactance decreases with higher frequencies. Because of these opposite characteristics, for any LC combination there must be a frequency at which the XL equals the XC as one increases while other decreases. This case of equal and opposite reactance is called resonance and this circuit is called as resonance circuit.
