A volt is one Joule of energy per unit Coulomb of charge.

A volt is the unit used for electric potential, which is NOT the same as electric potential energy!

We find the voltage (elec potential) several ways:
$V = W/q$
W = work
q = charge

$V= DeltaE/q$
$DeltaE =$ The change in the energy
q = charge

$V=I*R$
I = current
R = resistance

$P=I*V$
P = power

$P = V^2/R$
