PHY202 Lab 5 - Part 2- RCL Circuit

This part of the lab is done by using the PhET Simulator.

Start the simulation with the link appearing above and choose theRLCworkspace. Be sure to use the conventional current option during the exercise.

Part 2 - RLC Circuit

1. a circuit with an AC Voltage source in series with a resistor, inductor, and capacitor. Record the resistance. Set the capacitance to 0.1F and the inductance to 5.0H.
2. Click the AC voltage source element; set the voltage to 120V. Set its frequency to 1 Hz.
3. Using a single Voltage Chart device and two voltmeters (the max number of devices the prototype simulation supports concurrently) probe each element in the circuit, including the AC Voltage source. Make sure the polarity is consistent across the measuring devices.
4. Record the maximum and minimum voltages on each element. Take sufficient time to observe and qualitatively describe the similarities and differences in the voltage behavior across groups of circuit elements. Record your observations and answers to the questions that follow -Which circuit element(s) have in-phase voltage with the AC source? -Which circuit element(s) have out-of-phase voltage with one another, and by what degree (90, 180, etc.)?
5. Using the RMS voltage(Vrms=Vo2)show that the RMS voltage of the AC source is consistent with the sum of each element Vrms=[Vrms,R2+(Vrms,LVrms,C)2]
6. Using the resistance, capacitance, inductance, and the frequency of the AC source calculate the circuit's impedance Z. (See equation 23.7 in your textbook)
7. Measure the circuit current as it leaves the AC source using a Current Chart device or Ammeter. Record the maximum value of the current. Using the RMS current, show that the RMS voltage from the AC source is consistent with the RMS current and impedance.
8. Change the frequency of the AC source to the circuit's resonant frequency (as close as you can get to it). Allow the simulation to run for one minute to adjust. Repeat steps #4, 6 and 7. What similarities and differences do you see between the two rounds of measurements.
