As indicated in Eq. (2), electric charge
is usually measured in COULOMBS (abbreviated C).
If we take this as a fundamental unit, we can analyze
the definition of the volt (V) by reference to
Eq. (11): moving a charge of q = 1 C through
an electric potential difference
V
produces a potential energy difference of
J.
Therefore
If we prefer to think of the volt as a more fundamental unit,
we can turn this around and say that
However, I think the former is a more comfortable definition.
