Plot a graph of current I versus frequency f for different resistance R considered. From these graphs obtain the resonance frequency of the circuit. Resonance occurs when the reactance of the circuit is vanishes, namely when the impedance of the inductor ZL is equal in magnitude but opposite in phase with impedance of the capacitor Zc. Therefore the resonance frequency can be shown to be 1 2LC = Equation 10 Compare the value of the resonance frequency obtained from the experiment with the one calculated using Equation 10.
