Hi,

I have a problem about EMF and/or Voltage.
Let their are 100 electron at a place A and 200 electron at place B. Now what will be the Voltage/EMF (Voltage or EMF difference)?????

And How to calculate it ??

In other words "How can I calculate Voltage or EMF if I know only Charge difference" ????

By using Coulomb's law, force between two point charge and electric field due to a point charge at a distance r can be calculated.

But my problem is somewhat different. I don't want force or electric field, but voltage difference.

My question is like this Let in a battery at one node 1 Coulomb charge and at other node their are 10 Coulomb charge. Now I want to calculate Voltage or EMF (difference).

How to do that ???

V=Q/C

V=volts

Q=coulombs

C=farads
