136 Joules of work is expended in moving 8.5 x 1018 electrons from point x1 in a conductor to point x2 in the conductor. What is the potential difference (in Volts) between x1 and x2?

Pj Problem of Interest is of type force. Problems of voltage, energy, and work in an electric circuit are force problems.
1 Joule (J) of work is expended when 1 Coulomb (C) of charge is moved between two points at a potential difference of 1 Volt (V).
So, the relationship between work, charge and voltage is expressed as follows:
W = QV
Where W is work in Joules; Q is charge in Coulombs; and V is voltage in Volts.
So, 1 Volts = 1 Joule/1 Coulomb.
Charge of an electron = -1.602 x 10-19.
So, Total Charge = (1.602 x 10-19) x (8.5 x 1018)
Therefore, Volts (V) = 136 J/(1.602 x 10-19) x (8.5 x 1018) = 1360/13.6 = 100 V.
The point . is a mathematical abstraction. It has negligible size and a great sense of position. Consequently, it is front and center in abstract existential reasoning.
