Yes, I chose 1mA because the resistors were in k(ohms). 1 keeps the math simple, but you can choose whatever you want for a test voltage or current. Note if resistors were in ohms(no k) I'd likely choose 1A.

So what if you did a norton-to-thevenin source transformation on the test current, then you do mesh analysis on the resulting supermesh?

How do we know that Vab = Voc? Why doesn't the addition of the current source change the voltage for the open circuit?

What if I use redundant sources, for example VA-B is the same as the voltage across 1k resistor =1k*1mA=1v.

In summary, in a circuit with only dependent sources, Vth will be 0?

thanks sir, it was of gr8 help. respect from india! :)

Why is there no current source in the equivalent circuit? There is a dependent current source In the original circuit, so I think it must be have current source in the equivalent circuit.

How did you determine that the direction of the current in resistor 2 is going on the V1? Why not away?

thank you, your videos really helped a lot.

how would you do a nodal analysis if there was a resistor above the dependent source?

Why is it incorrect to solve for Thevenin without the test voltage/current source?

You messed up the nodal analysis, you used V2-V1 for both nodes

good video but if you're telling us a problem can be solved in two ways then solve it both ways ffs

This is incorrect. Vth should be 0 V for any circuit without an independent source. So Rth is always 0. All of your math looks correct from what I could tell by quickly glancing it over so not sure where you went wrong.
