1. The problem statement, all variables and given/known data Find the voltage across R1 (see attached image). Note that all values are known. 2. Relevant equations Voltager divider might be used. I hope KVL doesn't have to be used here. 3. The attempt at a solution My problem is that I don't know if the current from I1 is going into the path in which there is R3, because there would be current in the opposite direction (downwards) coming from I2. Do I need to use such anaylses as Thevenin or mess analysis to find the current through R1?
