Voltage and Current Laws in Multisim
This week's lab introduces you to the construction of a resistive network in Multisim. You will learn to utilize Multisim to confirm your calculations.
Please use the following documentation to help you setup tolerances in Multisim.
- Watch video entitled "Week 1 - Basic Components and Voltage and Current Laws in Multisim"
- Work Exercise 57 from Chapter 3. For the load resistors of 7 K? use the tolerance levels in the table to perform calculations of 'Vx' to fill in the 'Calculated Vx' in the table below.

- Construct Figure 3.93 in Multisim.
- Run simulation to measure the voltage drop across the 7K? resistor and record the measurements in the first box under 'Measured Vx' column.
- Now, add the tolerances to the resistor based on the tolerances in the table and run the simulation to complete the table. (Use this document to set up tolerances in Multisim: Setting Up Tolerances in Multisim)
- Take the screen capture for all the measurements of 'Vx'.
- Answer the following questions:
- Does the measured values match the calculated values? If not, explain why they are different?
- Describe the relationship between the resistance (7K?) and measured voltage 'Vx'?
- Explain the significance and the effect of adding resistor tolerances on your measurements of 'Vx' in Multisim?
- Create a new word document called "Lab1_StudentID.docx" with your GID substituted into the file name.
- 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.
