1. The problem statement, all variables and given/known data Which of the following are self-contradictory combinations of circuit elements? - A 2 Amp current source in parallel with a short circuit. 2. Relevant equations KVL- "the sum of voltages around a closed loop amounts to 0. KCL- "the current into a node equals the current out of a node. Ohm's Law- V= IR 3. The attempt at a solution The answer key says this is not contradictory, but I don't see how we can have such a circuit... If we had a short circuit parallel to a current source wouldn't all the current go into that short circuit branch and ignore the other branches? Then we'd just have a loop of 2 Amp current with no voltage drop... Why wouldn't that violate KVL?
