SI unit (symbol H) of inductance (the
reaction of an electric current against the
magnetic field that surrounds it). One henry
is the inductance of a circuit that produces
an opposing voltage of one volt when the
current changes at one ampere per second. It
is named after the US physicist Joseph Henry.
