Learn the pspice program to design and simulate circuits.
Procedure
Part 1. Build and simulate a simple circuit.
Part 2. Find the Thevenin equivalent of a circuit.
We set up a current supply with no current, and we steady increase this current and model it with a graph.
Data
The data obtained shows that the Thevenin voltage is 10V and the slope or Thevenin resistance is 3.33Ohms. Which means the Norton current is 3A.
We then replace the current supply with a variable resistor and we obtain this graph with the results. The vertex of this graph is where maximum power transfer occurs, exactly the value we obtained for the Thevenin resistance.
Pspice provides a good tool to model circuits that would otherwise required physical labor and plenty of mathematical calculations.
