What is the relationship between electric potential and work?

[QUOTE="jackarms, post: 4744482, member: 500976"] For 1: It could be for a variety of reasons. It might just mean that in the context only the magnitude of the potential matters, so you would just throw away the negative. It could also be that they do a bit of processing on the inside of the integral -- the integrand involves the dot product of the electric field and the displacement of the integration, so if this is negative they could have taken it out and canceled it with the other negative in front. For 2: I'm not quite sure what you mean -- the field can do both positive and negative work, and so can an external force. It just depends on the context. [/QUOTE]
