Resonance Review 11/9/07

XL = XC, fres=(2*pi*sqrt(LC))^-1, resonance effected by resistance (shifts fres). Skin effect in inductor needs to be considered. Should use series RLC circuit to reduce impact of resistance. Not sure if a high Q circuit would be beneficial.



At resonance the series resonant circuit appears purely resistive. Below resonance it looks capacitive. Above resonance it appears inductive.



Impedance is at a minimum at resonance in a series resonant circuit.
