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...
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...
