It could if it was still part of the lowest resistance path to ground.
Electricity is like water, it wants to flow from high potential difference to low potential difference.
Lightning (as far as I know) does not have consciousness and is not out to get your computer!
The parent post was talking about putting a automatic switch in between the power supply to the house (ground active neutral) and switching it off when lightning struck, the problem there is that the switch will not do much if the lightning air gaps around it.
- amelius 4y agoIsn't it more likely that the current will go from one terminal of the now unconnected cord to another terminal of the same cord?
- accountofme 4y agoIt all depends on the what is the shortest path to ground. Ground is also a relative term for a lightning strike. When lightning hits the ground, a potential field emanates from that point. The further out the closer to 0V the potential difference is. As such it depends on where the strike is in comparison to the house, your wiring, where your house is grounded etc. For example, if the grounding point on your house is very close to the strike, your house ground will be raised to the voltage of that point away from the stike. The path to 0V may be through your active wiring, your powesupply, the house frame or the water pipes. So yeah, hope that helps
