Law proposed by Georg Ohm in 1827 that states
that the steady electrical current in a
metallic circuit is directly proportional to
the constant total electromotive force in the
circuit. If a current I flows between two
points in a conductor across which the
potential difference (voltage) is E, then E/I
is a constant (which is known as the
resistance, R, between the two points). Hence
E/I = R. Equations relating E, I and R are
often quoted as Ohm's law, but the term
`resistance' did not enter into the law as
originally stated.
