The value of the R2 resistance is R4 A PR4 2) Three Loop Circuits (Mesh and Nodal Analysis) - Build the following circuit with R1 = 560 12, R3 = 10 kl, R4 = 10 k, and R5 = 100 in MultiSim and tune the potentiometer until the LED current (PR4) is as close to 6 mA as possible. Hint: Decrease the potentiometer increment to 1% to fine tune the resistance better. Take a screenshot showing all of the values. Using the Multisim LED voltage (XMM2 from Multisim), perform caculations Adjust the R2 Pot% until PR4 = 6 mA to solve the three loop currents Double Click on R2 and equal to the Pot % multiplied by 1k R2 (PR1, PR2, and PR3) using the 3- For example, 50% --> 500 change to 1% increment 31kQ Key=A PR1 loop mesh matrix solving A PRZ technique and use those values XMM1 to solve for XMM1 and PR4 using Module 1 techniques. NOTE: Use both packs in series. J PR3 PR4 will be equal to 6mA It should be around 9.6V. when VR5 = 0.6V because When doing calculations you will It must be > 8V or get new VR5 = 6mA/100 batteries. Use the measured need to replace the value in Multisim and for all potentiometer in the schematic hand calculations. XMM2 Make sure the smaller LED1 with the resistance (%*1k0). =Vs_2packs leg of the LED (cathode) is connected to ground. After solving with mesh matrix, do a source transformations of V1 and Vedi and calculate the node voltages using nodal matrix analysis and use the calculated node voltages to solve for PR2 and PR3. NOTE: You cannot solve for XMM1, PR1, or PR4 after doing the source transformations because those quantities are in the source transformation. Hint: It will be a 2 x 2 Nodal matrix problem after doing the source transformation. Question: Prior to the source transformation how many nodes are there in the circuit (include the reference node in your count)? * Finally, build the circuit and tune the potentiometer until XMM1 is equal to 0.6V and take a Photo.
