1. The problem statement, all variables and given/known data This is not a homework problem, but related to my circuits class. In the typical electrical engineering simplification, the resistance of wires in the circuit is taken to be 0 Ω. Also, the potential difference between two points along the same wire is 0 Volts. Does this mean that current through wires is undefined? Would engineers consider the current zero or infinite? 2. Relevant equations voltage = current * resistance 3. The attempt at a solution Maybe Ohm's Law does not apply here, and there is another way of looking at the situation.
