A Laboratory Experiment Involving a Parallel LC Circuit Containing a Real Inductor $(RL ≢ 0)$

A discussion of a laboratory experiment involving a parallel LC circuit containing a real inductor $(RL ≢ 0)$ is presented. By choosing component values to be confined to certain ranges, equations are presented for the (1) ratio of the output to input voltages, (2) Q of the circuit, and (3) phase of the output signal relative to the input. It is found that the phase goes to zero as the frequency decreases when a real inductor is used, rather than to $π/2$ as is the case for an ideal inductor $(RL = 0)$⁠. Experimental results are presented.
