SITUATION: Two people are debating electron flow versus conventional flow. One of them says that you will get different results predicting polarity of voltage drops in a resistive circuit depending on which convention you use. The other person says that the convention for labeling current does not matter at all, and the correct polarities will be predicted either way. QUESTION: Which of these two people is correct? Explain why, and give an example to prove your point.
