Voltage Dividers
Procedure:
Open Multisim Software
Program Files -> National Instruments (folder) -> Circuit Design Suite -> Multisim
START A NEW PROJECT BY GOING TO FILE>NEW>NI ELVIS I Design. You will get a workspace that has the connections you will find on our ELVIS board. Later we will see a 3-D Model of the ELVIS Board.
Part 1:Build a Voltage Divider and Test it with Loads.
In the next step the load is attached as asked in the table and readings are taken

Which load affected the voltage divider the most (highest % difference)?
Which load value resulted in the highest power dissipated in the load resistor at Va
Which load value resulted in the highest power dissipated in the load resistor at Vb?
Which load value resulted in the highest power dissipated in the load resistor at Vc?_____________
Is it the same load resistor for max power transfer for Vb and Vc? _________________
