Homework Statement I know that the work done by an electrostatic force is given by : W = Fdcosθ (scalar product) W = qE d cosθ and I know that the electric potential is V = -W/q , where the work here is the work done by the electrostatic force. 2. The attempt at a solution...

mmmm, I see Thanks :)

you said it is " the amount of charge which results from a current of one Ampere flowing for one second " ,, what is Ampere ? and how would we find it ? ( suppose we want to calculate the charge and the magnitude of the charge is not given)

I know that a charge is discribed in terms of coulombs. But how did they know that an electron has a charge of 1.60217646 × 10-19 coulomb ? by the way , what is a coulomb exactly ? and how did they found or discribed its quantity ? I would like the answer to be in details please . Thanks
