For instance, at a certain frequency,
the signal may be detectable first at a strength of 20 Microamps of electricity.

If the signal has to be increased to 50 Microamps to notice a difference,
the JND in that case is 30 Microamps.

When they took that rust-coated iron and flowed saltwater solutions of varying concentrations over it,
they found that it generated several tens of millivolts and several Microamps per cm2.
