1. The problem statement, all variables and given/known data Determine the voltage across the 2A current source 2. Relevant equations kirchhoff voltage law (kvl) kirchhoff current law (kcl) ohm's law 3. The attempt at a solution I'm new to the concept of a current source. I'm not sure how there can be voltage drop across the current source, so maybe the question is asking for the voltage drop across the 10 ohm resistor that's in series with it? Are all resistors that are parallel with the power source going to have a voltage drop equal to the source voltage? So the voltage across the 5 ohm resistor and the current source is 50V? I doubt the answer could be that simple though I think I'm really missing something to understand how to do this question. If I need to do KCL, it would have to be at the first junction the 2A flows into right? and for KVL, it would be the loop with the 50V power source? Having both equations is leading me nowhere Thanks!
