1. The problem statement, all variables and given/known data Determine the Thevenin equivalent of the following circuit: https://imgur.com/a/74UjA (Top image) 2. Relevant equations - 3. The attempt at a solution The last 3 images in the Imgur album are all different approaches. I can't figure out what the right one is, and why the other ones are wrong. I spent hours searching on google, and I feel like I understand Thevenin/Norton well -now I am not so sure..-, but to no avail. Extra information: - Ub = Usource - "zal door Rv gaan" means "will pas through Rv" EDIT: I think my second attempt is correct. Uth = 5V. The 1st and 3rd method are presumambly wrong. I sort of have an idea of why, but I am still not 100% convinced.
