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#
