Questions

1. Derive Equation using impedances (, and ). From Equation show that the resonance frequency is given by Equation .
2. Determine which of the three values of inductance for your coil is most accurate 1) the value estimated in Lab 5 using the time constant of an RL switched circuit, 2) the value estimated using the resonant frequency you obtained using manual frequency response measurements, or 3) the value estimated using the resonant frequency you obtained using LabVIEW to automatically measure the frequency response. Justify your answer and explain why the other values are less accurate.
