## RC Circuits in Multisim

This week’s lab is based on the application of circuit analysis techniques to evaluate an RC circuit in Multisim.

1. Watch video lecture entitled “Week 4 – RC Circuit in Multisim”.
2. Work Practice Problem 8.13 from Chapter 8 to determine the capacitor voltage ‘V’ for t >0 and record the value in the table.
 Calculated Measured Capacitor Voltage ‘V’
1. Construct Figure 8.46 from Chapter 8 in Multisim.
1. Run simulation to measure the voltage across the capacitor ‘V’ (Use 5% tolerances for each of the resistors)
2. Take the screen capture for the measurements for ‘V’.
2. Answer the following questions:
1. Are the measured values same as calculated values? If not, explain why they are different?
2. What is the circuit time constant ‘τ’?
3. Is ‘V’ a natural, forced or complete response? Explain why?
3. Create a new word document called “Lab4_StudentID.docx” with your GID substituted into the file name.
4. Save the analysis from step 2 and simulation results from step 3 along with the table and screen captures of all the measurements. Make sure to answer the questions in step 4.
5. Upload file “Lab4_StudentID”.
