What is resonance in a series LCR circuit ? Derive the expression for resonant angular frequency . |
|
Answer» SOLUTION :The phenomenon of IMPEDANCE of the series LCRcircuit becomingminimumand current in the circuit becomingmaximumat a PARTICULAR frequencyof the appliedalternatingvoltage is called electrical resonance . At resonance , `X_C=X_L` or `1/(W_0C)=W_0L` `rArr W_0^2=1/(LC)` or `W_0=1/sqrt(LC)` If `gamma_0`is the frequencyof the appliedalternatingvoltage when the series LCR circuit is at resonance , `W_0=2pigamma_0` `2pi gamma_0 =1/sqrt(LC)` `gamma_0=1/(2pisqrt(LC))` |
