Does U=qV or -qV? I notice my textbook uses qV but

[QUOTE="belledona, post: 5948860, member: 641596"] Hi I have a question about electric potential! Since the negative sign isn't used in U=qV, and a-b is used for subscripts, then that takes care of the negative. But what about using U=-qV? An online lecturer uses U=-qV, while my textbook uses U=qV and then uses -qV to explain the force used to move a charge AGAINST the electric field. I'm wondering if qV or -qV is convention, because -qV is easier for me to understand conceptually but I lose the negative sign sometimes during problems... Thank you! [/QUOTE]
