Never mind, did superposition incorrectly. 1. The problem statement, all variables and given/known data Find Vload using superposition and thevenin's equivalent 2. Relevant equations 3. The attempt at a solution Well for network on the left of Rload, I found Vth = 5 V and Rth = 15.1 kohms For the network on the right of Rload, I found Vth = 7.5 V and Rth = 8150 ohms. So using superposition I would do: 1) 5 V * 10k / (10k+15.1k) = 1.99 V on Rload 2) 7.5 V * 10k / (10k + 8150) = 4.13 V Adding those I get 6.12 V. However, when I simulate this in PSPICE I get 4.33 V. I also checked each side and I get 1.99 V on the left (when I disconnect the right) and I get 4.13 V on the right (when I disconnect the left). What am I doing wrong, I can't even remotely see where that 4.33 V comes from.
