Obtain the resonant frequency `omega_(r )` of a series LCR circuit with `L = 2.0H. C = 32 mu F` and `R = 10 Omega`. What is the Q-value of this circuit ? |
Answer» Given, `L = 2H, C = 32muF, R = 10 Omega` Resonant angular frequency `omega_(r )=(1)/(sqrt(LC))=(1)/(sqrt(2xx32xx10^(-6)))=125` rad/s Q-factor of this circuit, `Q = (1)/(R )sqrt((L)/(C ))=(1)/(10)sqrt((2)/(32xx10^(-5)))=(10^(3))/(40)=25`. |
