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 ??

😕

    Coulomb's Law is the answer -

    Voltage difference = (1/4*pi*Epsilon0)*(q2-q1)/d

    - Epsilon0 = Permittivity of free space
    - q2 = Total charge at Place B
    - q1 = Total charge at Place A
    - d = Distance between A and B

    from coloumbs law of electrostatic force... v can calculate voltage (potential difference)
