To determine the unloaded source voltage  and the internal resistance  of the voltage source model:

  1. Measure the open-circuit voltage
     
  2. Connect a variable load  and adjust its resistance until
  3. Disconnect  and measure its resistance, as it should be equal to the internal resistance, based on the maximum power transfer principle
     

(voltage divider, two resistors with the same resistors will have an equal voltage across each of them

  1. Use source transformation to identify  and  for the current source model
