1. The problem statement, all variables and given/known data I have two questions. 1) The ends of a length of wire are labeled a and b. If the current i from a to b is negative, are electrons moving toward a or b? 2) We have a circuit element with terminals a and b. The voltage and current from a to b are both positive. If electrons carry the charge, which terminal do they enter? 2. Relevant equations None, this is a conceptual problem. 3. The attempt at a solution For question 1), I concluded that a negative current from a to b means that electrons flow from a to b. This makes sense and is the correct answer. For question 2), I concluded that electrons flow from b to a since the positive current goes from a to b, but this is not the answer in the book. Is the book wrong? Or am I missing something?
