ET310 Week 3

 
Capacitive Circuits in Multisim
This week’s lab is based on the application of circuit analysis techniques to a capacitive
circuit in Multisim.
1. Watch the video lecture entitled “Week 3 – Capacitor Op-Amp Circuit in Multisim.
https://content.grantham.edu/at/EE310/week3_video.zip

2. Construct Figure 7.36 in Chapter 7 (Example 7.11) with Vs = 3sin200tV, R1=20kohms,
Cf=5uF, and Vc(0) = 1.5 and find the output voltage ‘Vout’.
3. Interchange the positions of the capacitor and resistor and compute the output voltage
‘Vout’ and record the values in the table below.

                                                                                    Measured  Vout              Calculated Vout
 Correct positions of R1 and Cf
Interchanged positions of R1 and Cf

4. Construct Figure 7.36 from Chapter 7 in Multisim.
a. Use the function generator to provide Vs to the circuit and run simulation to measure
the Vout using Oscilloscope. (Use 5% tolerances for the resistor)
b. Interchange the positions of the resistor and capacitor and run the simulation to record
the measurements of ‘Vout’ in the table above. (Use 5% tolerances for each of the
resistors)
c. Take the screen capture for the measurements for ‘Vout’.
5. Answer the following questions:
a. Are the measured values same as calculated values? If not, explain why they are
different?
b. What type of a circuit does Figure 7.36 represent? Provide a practical use of this kind of
Op Amp Circuits.
c. When you interchange the resistor and capacitor, what type of a circuit is obtained?
Provide a practical use of this kind of Op Amp Circuits.
d. Use the results obtained from ‘Vout’ to explain the differences in these two circuits.
6. Create a new word document called “Lab3_StudentID.docx” with your GID substituted
into the file name.

Add Multisim files as an attachment.
