PSpice

Objective
Learn how to use PSpice.

Part 1
Build and simulate the circuit:

Part2 
Find the Thevenin equivalent of the circuit:

Graph

plot V v.s I and the slope is the Thevenin resistance.

From the graph we can see m=(10-7)/(-0.9)=3.3Ohm

Then, replace the current supply by a changing resistor. And Plot Power v.s Resistance. From the graph, find max power supply.















Since max power occurs when R_load =R_thevenin, the theoretical R should be 3.3Ohm. And the result from the graph also shows the max power occurs when R is at about 3.3Ohm. We verify the max power theorem by graphing on PSpice.

Conclusion
PSpice is an awesome tool for simulating circuits!!!
