1. The problem statement, all variables and given/known data Just refer to the figure. The part shown is a part of a big circuit which you and anybody else shouldn't worry about. 2. Relevant equations 3. The attempt at a solution I considered the battery terminals to be at 10 and 0V respectively. So the farther end of the resistor should be at 5V. An inductor produces a back EMF, which means that along the direction of current, there is a voltage drop. Therefore, A will be at 5V. So V(a)-V(b)=0. Am I right? I would be grateful to anyone who can help me solve similar problems, especially the ones which involve capacitors too. When does the "voltage" drop and when does it rise?
