How to determine between norton and thevenin

Hey,

I am a bit stumped on a text book question.

I've attached the diagram to help.

The questions states:

Two circuits shown below are in identical black boxes with ONLY their terminals accessible from outside the box.

How could you determine which box contains the Norton equivalent?

What I think:

Since Rnorton = RThevenin, we cannot find out by shutting of the current and voltage sources (I.E current source becomes open circuit / voltage source is short circuit) and measuring the resistance since Rnorton = RThevenin...

I believe the answer is that we cannot determine one from the other since this is exactly the theorem... both circuits are equivalent to any device we place on the exposed nodes.

Does this sound correct?

Thanks!

Sounds correct to me.

OK Thank you JimB

Norton involve current while thevenin theorem involve voltage..correct me if wrong

I agree with you in your answer.

I Edited this becuase, i checked and i realized that what i wrote was wrong.
