    Calculate Voltage or EMF from 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...

    Calculate Voltage or EMF from Charge difference

    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...
