Let me set the scene:
- Macbook with metal case plugged into the wall with 3 pronged plug
- iPhone is plugged into an iPad charger with 2 prongs
When I touch both my iPhone and the case of my macbook I perceive a mild 'electric shock' which continues as long as I am touching both devices.
I assume that there is an air gap in the iPad charger so there should be no current flowing between the iPhone and the macbook.
I can't make any sense of what's going on and if someone could school me as to what's happening I'd be very grateful.
