Homework Statement



Find the thevenin voltage and thevening resistance of the circuit.

The Attempt at a Solution



The posted answers for the question are 5v and 1k ohm. But I can't see how the thevenin resistance is 1k ohm. Can anyone explain? I see the 5 and 1 being in parallel giving 5/6 k ohm.

edit: think I figured it out as I posted it. current sources get replaced by open circuit to calculate thevenin resistance

Yes, that's correct. You set sources to 0, so a current source would be replaced by an open circuit since no current flows through it.
