1. The problem statement, all variables and given/known data The question is in the photo attached. 2. Relevant equations 3. The attempt at a solution I have found the Thevenin voltage as the 10 and 20 ohm resistors are in series (30 ohms) and the 50 and 40 ohm resistor are in series (90ohms). The 30 and 90 ohm resistors are in parallel so 30||90 = (30×90)/(30+90) =22.5 ohms I am having struggles with determine the Thevenin voltage as the solution says the 8 A current gets divided equally among the 10 and 20 ohm resistor but I don't understand why.
