Work in a uniform electric field

[QUOTE="malek2771999, post: 6018540, member: 647738"] I need a little help here when calculating the work done in a uniform electric field on a positive charge to move it from point a at higher potential to point b at lower potential that means the charge is going towards the negative plate we first use V = - ED and then we have a negative V then we use W = qv and we have a negative work that means the work is done by the system not external force and that's what happened because a positive charge in a electric field will always go towards the negative plate is everything I did here correct? Because in my textbook the formula for work is W= - qv and it's confusing me please help my exam is tomorrow :) [/QUOTE]
