Data Sheet
Pre-Lab Work (Hand Calculations and/or LTSpice Simulations)
Part 1
a) Build circuit 1 in LTspice and run a DC simulation




Include a screenshot of your LTSpice circuit here (Have a look at an example screenshot at the
end of this document):




Simulated Results

Node Voltage at N1 Node Voltage at N2 Node Voltage at N3

= 3V = 662mV = 0V

, b) Build circuit 2 in LTspice and run a DC simulation:




Include a screenshot of your LTSpice circuit here (Have a look at an example screenshot at the
end of this document):




Simulated Results

Node Voltage at N1 Node Voltage at N2 Node Voltage at N3

= 0V = 551mV = 5V

, c) Build circuit 3 in LTspice and run a DC simulation:




Include a screenshot of your LTSpice circuit here (Have a look at an example screenshot at the
end of this document):




Simulated Results

Node Voltage at N1 Node Voltage at N2 Node Voltage at N3

= 3V = 1.21V = 5V

Do the node voltages from the first two circuits sum to match the voltages of the third circuit?
Note any additional observations. What circuit analysis technique does this demonstrate?

The sums of nodes in part a and part b equal node voltages in part c. Node 1 0+3=3, node 2 0+5=5, and
node 3 662+551=1.213. This simulation shows the superposition theorem.
