The Thevenin-equivalent resistance is correct.
You need to find the open-circuit voltage between a an b. If it is open no current flows through the 100 ohm resistor, so all the 2A current of the current generator flows to B and then to A, through the 200 ohm resistor. So you know at VB-VA.

So, there's an incorrect equation, right?

ehild · Jun 30, 2012

Yes, the second one.

Is it just (VB-VA)/200=2?

ehild · Jun 30, 2012

Yes.
