RC Circuits in Multisim

Work Practice Problem 8.13 from Chapter 8 to determine the capacitor voltage ‘V’ for t >0 and record the value in the table.

• Construct Figure 8.46 from Chapter 8 in Multisim.
  • Run simulation to measure the voltage across the capacitor ‘V’ (Use 5% tolerances for each of the resistors)

• Take the screen capture for the measurements for ‘V’.

• Answer the following questions:
  • Are the measured values same as calculated values? If not, explain why they are different?

• What is the circuit time constant ‘τ’?

• Is ‘V’ a natural, forced or complete response? Explain why?

• 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.

Sinusoidal Steady State Analysis

1. Work Practice Problem 10.10 from Chapter 10 to determine the currents I1, I2 and I3.

• Switch the places of capacitor and inductor and repeat step 2 to determine the currents.

• Record the values in the table below:

• Construct Figure 10.21 from Chapter 10 in Multisim.

1. Run the simulation to measure the currents I1, I2 and I3. (Use 5% tolerances for the resistor)

• Perform Steady State AC Analysis and trace the voltage across the capacitor.

• Take the screen capture of all the measurements and the AC analysis.

• Answer the following questions:

1. Are the measured values same as calculated values? If not, explain why they are different?

• Explain if the circuit is linear or non-linear?
  • Compare the measurements of currents from step 2 and 3 and explain the differences?

• What do you understand from the steady state AC analysis of this circuit?

• Save the analysis from step 2 & 3 and simulation results from step 5 along with the table and screen captures of all the measurements. Make sure to answer the questions in step 5.
