1. The problem statement, all variables and given/known data (see attached file) 2. Relevant equations Kirchhoff's laws 3. The attempt at a solution (see attached file) I only included the work for measurement 1 since measurement 2 follows from that. I got both voltage values correct. However the paths of the current flow was incorrect for both measurements. (See the attached file for solution) It specifically states that "Arrows to show that the current is only in the left hand loop i.e. not through R3." are needed, but I also included arrows for the RH loop. My question: Why is there no current through the RH loop i.e. through R3? Is it because the voltmeter in that loop has an infinite resistance? If yes does this always apply?
