A parallel R-L-C network is demonstrated in figure below, here the inductor is seem as non-ideal having the resistance, R, related with the winding. Verify an expression for the resonant frequency at that the impedance becomes purely real or say resistive in terms of the network elements. Therefore, establish an expression for the value of such resistance at the resonant frequency as the network elements. For the values of the components specified, find out the value of the resonant frequency and the magnitude of the resistance.
