In my region, there is some kind of folk belief about lightning. I personally think it is nonsense, but I'm asking to make sure it sure is nonsense. After all, I can't pretend to know much about electricity. Anyway, it is said that when there is a thunder storm near your house, then it is best to unplug all the appliances, but leaving at least one plugged in. The idea would somehow be that when the lightning strikes, then by leaving one appliance plugged in, the lightning "will have somewhere to go" so it won't cause damage outside this one appliance. So, am I right in thinking that this is nonsense?
