The College Board has developed the "AP Central" website to provide resources for teachers seeking to improve their students' performance on AP exams, including human geography, chemistry, and European history. This particular resource is from the AP chemistry course page, and it deals with common difficulties and misconceptions regarding electrochemistry. Written by Senior Lecturer Emeritus George Miller of the University of California, Irvine, this article offers some basic guidelines for educators grappling with this particular area of chemistry. The piece includes a discussion of galvanic cells, Ohm's Law, and the half-cell model. Throughout the text, Miller does a fine job of identifying potential areas of confusion that frequently trip up students studying electrochemistry.
