Hey,

For the attached question, the only part I do not understand is why the Thevenin Resistance is equal to R3.

I thought it would be (R1 || R2) + R3

Can somebody please explain this?

cheers!

The second hand drawn figure shows it. R1 and R2 are not in parallel. They are in series and their series connection is in parallel with a short circuit, so the equivalent resistance of this connection is zero.
