Should be pretty close....the main component of a galvanic isolator is a
bit of
solid state electronics that allows current to flow one way, but not
another.
(I think it's a diode, but 296 people will correct me if I'm wrong.)



Here is one correction (295 to go....)

The isolator doesn't favor one direction over the other. It uses diodes in
parallel facing opposite directions so that an AC current can still flow
either way. The purpose is to require that the voltage be higher than what
galvanic action would generate. A couple of diode drops would require a
voltage of 1.4 volts, more than any likely galvanic action but not enough to
create a shock hazard.
