1. Procedure 

Figure 1: Resistor circuit 

• For the circuit in Figure 1, set V1 to 3 V, V2 to 1.5 V. Select R1, R2 and R3 at random from the resistors supplied to you 

1. Paper Calculations 

• Use the Mesh Analysis technique.  

• Determine the resistor values. 
• Calculate the voltage drops across each of the resistors in turn. 
• Calculate the values of I1, I2, I3 and V_Node, as indicated in Figure 1. 
• Include the paper calculations in your report. 

1. Simulation 

• Simulate the circuit in Figure 1 using a program of your choice. 
• Record the indicated values /observations for your combined report. 

1. Practical 

• Do NOT connect both supplies together without a resistor(s) in between! 
• Verify the electrical connections are correct before supplying power to the circuit. 

• Record the results/observations for your report.
