RLC CIRCUITS Goals: Understand the behavior of RLC circuits. Equipment: This lab uses a simulation and no other equipment InstrUCtionsz For the entirety of this lab, you will need to start the simulation program https:[thetcoloradoedu/en/simuIation/circuit-construction-kit-ac-virtua l-Iab (Ph ET \"Circuit Construction Kit (AC+DC), Virtual Lab\") This is a JAVA software. You can download for free. https:[/www.iava.com/en/down|oad[ 1. PART 1 LC CIRCUITS Create a circuit with a battery and a capacitor in series. Right click on the capacitor and choose the option \"Change Capacitance\". Choose a value for the capacitance (right click on capacitor) and write down its value. Once the circuit is closed, the capacitor will start charging (you will see excess charges in the plates). Describe your observations Press the \"Pause\" button and disconnect the battery (right click to split a junction). Remove it from the simulation. Connect an inductor in series with the capacitor. Right click on the inductor and choose the option "Change Inductance\". Choose a value for the inductance and record its value. Press the \"Play\" arrow. Describe your observations. Click the \"Current Chart\" and place the detector on a wire in the circuit between the inductor and the capacitor. You can adjust the yaxis using the +/ buttons so that you can see the full curve. Write down the maximum/minimum current and estimate the period of the oscillations. 4. Convert the period you obtained on question 3 to an angular frequency in). Also calculate the angular frequency m0 = 1/\\/LC for an LC circuit, using your values obtained on questions 1 and 2. Compare these two angular frequencies. 5. Click the \"Voltage Ch art\" and connect the detector to both sides of the capacitor. Adjust the y axis to see the full curve. Write down the maximum/minimum voltage and estimate the period of the oscillations. Describe any similarities you observe between the voltage and current charts. Include a snapshot of your circuit, showing the current and voltage charts. PART 2- RLC CIRCUITS 6. You may want to reset all or add to your circuit. 0 Connect an AC voltage in series with a resistor, inductor and capacitor. 0 Choose values for the resistance, inductance and capacitance. 0 Write down your chosen values here. Adjust the voltage and frequency of the AC source and write down your chosen values. 7. Place voltage charts for each component in the circuit, including the AC voltage. Make sure the polarity of your charts are consistent. Describe, without trying to explain, the similarities and differences between the graphs. ** If your graph looks like a straight line, make sure you change the y axis values by pushing + to zoom in. 8. Using the resistance, capacitance, inductance and frequency of the AC source, calculate the impedance Z and the expected 1mg. Hint: In a AC circuit, the rms current is related to the impedance by the relation. Irms = ErmS/Z Where the Erms for a sinusoidal AC source is Erms = EO/ 9. Place a current chart after the AC source in the circuit. Using the RMS current, show that the RMS voltage and current are consistent with the impedance. 10. Change the frequency of the AC voltage to the resonant frequency and click on \"Reset Dynamics\". Leave the simulation running for at least one minute while the circuit adjusts to the changes. Repeat questions 7 to 9 and comment on the similarities and differences between the tests. Include a snapshot of your circuit
