Question 1: Is voltage measured as the amount of work a charge can do as it flows between two points because work is proportional to force? Thus by measuring the amount of work a certain amount of charge is doing as it flows between two points, we are able to indirectly measure the electromotive force acting on that charge?
Question 2: Do we measure electromotive force this way because it is somehow easier to measure the loss of energy of the charge than the force acting on it?
Question 3: Work is equal to Force x Distance. Does this then mean that we could increase voltage by increasing the distance between the two points we are measuring? Obviously not, since this isn't true in practice. So how does distance affect electromotive force, if at all? It seems as if it shouldn't affect it at all if voltage is truly a force.
Please note: I've seen some explanations involving calculus, which I don't know. My math knowledge is only up to pre-calc.
Thank you for your help.
