PSpice for Thevenin and Norton Equivalents and Max Power

In this assignment we learned how to use PSpice to find Thevenin and Norton Equivalents. But to be familiarize with the program we first created a simple circuit to find the voltages on each nodes. To accomplish this, we used DC Sweep, a feature used in the Schematics.
 

 

Now to find Thevenin Equivalent, we draw out our new circuit and then place a current source where the Thevenin Voltage is to be found. just like the figure below.

 

Running the DC Sweep will give us the graph that looks like this:

  

The zero x axis of the graph will point out the Voltage Thevenin and the slope will give us Thevenin Resistance.

To find the Norton Equivalence we must remove the current source on the far right of the circuit and place a voltage source.

 

 The zero intercept of this graph will give us the Norton Equivalence and the slope of this graph will be the Norton Inverse Resistance

 

 In this Thevenin Equivalent circuit, we are going to find the maximum power that the resistance load will dissipate in the circuit.

With the help of PSpice, this figure shows that the max peak of the graph is the max power, which is 250 microwatts.
