Miguel ArrozOne mystery of Apple hardware with any metallic surface is why I feel the slight vibration or electrical current flowing through me when I move my fingers over the surface with the device plugged in to a 230V 50Hz outlet but not on a 120V 60Hz one.
Olivetree@arroz I have that feeling with some fridges, my S10 and anything that's has a metallic shell (and is not grounded?). But why does it only happen when *moving* the fingers?
@olivetree Probably because when they are stopped, current is flowing steadily and it’s not strong enough to be felt. When the fingers move, flow starts and stops quickly due to each tiny area of the surface and fingers textures gaining and loosing contact as they move. Maybe.
