ELECTROMAGNETIC OSCILLATIONS
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 VR(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.
