A. AC Voltage 1. Using the equations presented in the Theory, calculate for the rms and period of a (1) 4Vpk, 1kHz and (2) a 220V, 60 Hz ac signals. Record the values in Table 10.1. Table 10.1 Computed rms and peak and period of various ac waveforms Signal Rms peak Period, T 1 4Vpk (given) 2 220V (given) 2. Connect the circuit in Figure 10.8. Click on the voltage probe and tick the "Periodic" option. The probe will show the peak to peak, the rms, and the frequency. PR1 1 V1 R1 4V 1kQ 1kHz 0° 0 Figure 10.8 3. Run the Interactive simulation. Read the values shown in the probe and record in first row of Table 10.2. Table 10.2 Measured values of rms and period for two ac signals Waveform Calculated Rms (Table 7.1) Measured rms 4Vpk signal Calculated Vpk Measured Vpk 220V rms 4. Click on the Grapher View. The Document will appear. 5. In the Document, scroll down to the Axes, and set the time from 0 to 20 ms and the voltage from -5V to +5V. Click on any space in the document to update the graph. 6. Draw the plot in Graph 1. Graph 1 Q&A Box 1 ? How many complete cycles are displayed? Answer: 7. Replace the input with a 220V rms, 60 Hz signal and run the interactive simulation. 8. Repeat procedure 3 and record the value in row 2 of Table 10.2. 9. Compare the calculated rms/peak voltage for the two ac sources in Table 10.2 with the measured values. Write your answer in Q&A Box 2. Q&A Box 2 ? Do the measured values agree with your calculated values? Answer: 10. Repeat procedure 4. 11. Change the time from 0 to 20 ms and the voltage from -350 to +350V. 12. Draw the plot in Graph 2. Graph 2 Q&A Box 3 ? How many complete cycles are displayed? Answer: 13. Using the computed time period for one cycle in Table 10.1, explain how the time settings of the grapher affect the number of cycles displayed for each signal. How should you set the time if you wanted to see one to two cycles only for each signal? Q&A Box 4 ? How did the time settings of the Grapher affect the number of cycles displayed? Answer: Q&A Box 5 ? How should you set the time if you wanted to see one to two cycles only for each signal? Relate your answer to the period of the signal. (Should it be greater than the period, equal to the period, or less than the period) Answer: ~
