How to use in-sentence of “Electric potential”:
+ Technically, the voltage is the difference in electric potential between two points and is always measured between two points.
+ It is electric potential energy per unit charge.
+ Both electric potential and voltage are things we measure and the volt is the unit of measure for both.
+ In electricity it is very often more useful to use electric potential, the EPE per charge, instead of using the total electric potential energy.
+ Voltage is an electrical potential difference, the difference in electric potential between two places.
+ In another place, maybe another place in the same electric circuit, there might be an electric potential of 5 joules per coulomb.
+ Charges will always go to where they have lower electric potential or potential.
+ Similarly, we could have 100 coulombs of charge with 1000 joules of electric potential energy stored somewhere, maybe in an electric circuit.
