**Example 4.2-2: Analyze a rearrangement of the RLC components into a parallel configuration. **

As observable by the following figures, the resonant frequency and impedance value remain the same for the parallel RLC circuit. What may be understood by this is that the reactance of the inductor cancels out the reactance of the capacitor at this frequency of 505 MHz.

The input admittance of a parallel resonant circuit is: Y = (1/R) + jwC + (1/jwL).

The angular frequency, w = 2*pi*f = 1 / (sqrt(L*C)).
