For example, in the Netherlands you are not allowed to have more than 4 separate circuits on one GFI, that is a GFI with 30mA tripping current. ... Ohms law gets a little attention, ...

In a review just published in Nature Materials, researchers take aim at the oldest principle in electronics: Ohm's law.

Breaking inversion symmetry in materials allows deviations from Ohms law, enabling nonlinear effects that could drive future ...
