McMaster University 1EL3 Lab 6 Thevenin’s Theorem Introduction The purpose in this experiment is to study the Thevenin theorem. The theorem works by making complicated circuits easier to work with. By only leaving one source in the circuit and one resistor. Then calculating Rth and Eth across the load point we need.

V load = VR2= 6v - To calculate Thevenin resistance in step 3-5: replace voltage sources by short circuit and current sources by open circuit. Measure resistance at the load.
