Thevenin, Norton and Maximum Power Transfer Theorems
Write these on white board
RTH = 5kΩ
VTH = 10V
Now you can place any load in the circuit you want and the calculations are EASY!
Solving for VTH
VTH = VA – VB = 5V
What is the resistance from point a to b?

Solve for VL using traditional Ohm’s Law technique, Mesh Analysis, and Thevenin Analysis
What circuit analysis technique can we use to solve for this?
Thevenin’s Theorem. RTH = 5kΩ
I’ve checked this technique using Ohm’s law and it works. See following numbers:
5mW @ 5kOhm
4.94mW @ 4kOhm
4.96mW @ 6kOhm
