Question 1:

Compute the resonant frequency fo for the series RLC using equation (2) and compare it to the measured value.

Answer 1:

Considering the values used for the experiments: C = 1.0 µF, L = 20mH we can compute the resonant frequency as follows:

Question 2:

Compute the magnitude and phase for the series RLC circuit when the reactive component equals the resistive component.

Answer 2:

The impedance of the series RLC circuit is defined as:

Reactive component equals the resistive component implies:

The magnitude results:

The phase is computed as follows:
