A former high school student of mine in Europe was electrocuted while cutting grass with an electric lawn mower. This wouldn’t have happened in the US, because we use 110-volt current.
If an American baby gets loose and decides to munch on the power cord of an appliance, he will get a zap that tells him not to do that anymore. In Europe, the baby would probably die.
In Western Europe (not Eastern), the whole society is very safety conscious. Yet they still use 220-volt electrical current. Why?
