Consider an positive electric field and a positive charge, q inside this field. Suppose the FIELD does work on this charge and takes it from point A to B. Now i am trying to figure out what sign i have to put with this work..

which equation should i use here?

W= - (delta V) x (q) [V=voltage W=work done by field q=charge]

W= + (delta V) x (q)


Thanks...

I'm trying to remember what the convention is...positive charge in a positive field...negative, but I'm not absolutely sure on that...that probably something you could google.
