Are the results what you expected? ANS Yes, since R1 to ground is in parallel/ shunted with the voltage source we expected the voltage from R1 to Ground would be 5V. The results of the simulation will be displayed on the DMM. In the simulation toolbar the RUN button was clicked to measure the voltage in each case in step 6. To measure voltage, the V and COM were connected to the desired ports: a. In Multisim we found the NI ELVIS Digital Multimeter to measure voltage in our Wheatstone Bridge.

We saved our circuit once we were done building it. In the schematic, the circuit in figure 1 below was built.

Open a new schematic by going to File New Schematic capture. Open Multisim be double clicking the shortcut on the desktop. PROCEDURE Part 1: Simulation in Multisim:1. Required Components: o Multisim 11.0 or higher o NI ELVIS II o 4- 1kΩ Resistors o Electrodes (2 per team member) o 2 Alligator to Alligator clips o Connector wires Prototype a Wheatstone Bridge on the NI ELVIS II demo board and measure the unknown resistance of an arm. Troubleshoot a Wheatstone Bridge in Multisim.
