You know those problems where you have a circuit and then it's switched from A to B and it says something like "What is the voltage across the resistor"? Well, I know you have to use the loop rule, but I am a little confused on whether or not you have to add or subtract the voltage across the resistor in the loop role. So if you're going with the direction of current, I know you do -IR and +the EMF, but is it + the voltage of the inductor, or minus? If that question is strangely worded I apologize.
