## Main Question or Discussion Point

What is the most general method that can be used to get the Thevenin equivalent for a circuit (one that always works)?

1)Remove the load.

2)Find the open circuit voltage across terminals AB (Vth)

3)Find the resistance looking in from the terminals (Rth) by shorting the voltage source or replace a current source with an open circuit.

What if you had dependent sources in that circuit? How would you find the resistance looking into the terminals? You can't short/open circuit dependent sources.3)Find the resistance looking in from the terminals (Rth) by shorting the voltage source or replace a current source with an open circuit.

Yes, the method is applicable on all type of circuits.

Hi U can visit www.powerelectrical.blogspot.com to see about Thevenin's theorem and more topics in theorems. Also to get clear idea when dependent sources present visit ths link
