1.    From your measurements in procedures 2 through 4, determine C and L by using the measured value of the time constant t in each case. (Do not forget the resistance in the inductor). Enter the results in cells E55 and E57.

2.    Using the values of L and C obtained above, calculate the resonant frequency of the LCR circuit using:
 

3.    Plot V_R(y-axis) vs. f (x-axis) for procedure 9. From the graph, determine the best value of the resonant frequency and enter the result in cell E61.

4.    Compare the resonant frequency with that calculated from L and C and with the observed LC oscillation frequency. Compute the percentage difference and enter in cell E63.

5.    Answer Question 1 on the Worksheet and turn in as part of your report.
