1. The problem statement, all variables and given/known data Looking at the open circuit demonstrated in figure 2 (see attachment), what is the current through the ammeter? What is the voltage at point p? 2. Relevant equations 3. The attempt at a solution I am assuming if it an open circuit, I would think that the current would be zero (I might be wrong though). Meaning that since the current is zero, so is the voltage. I have a feeling I might be wrong though... Any help would be great!
