Why do some countries have differently shaped electrical outlets/adapters?
In: Technology
Most countries developed their own standards when electricity started being used. Some were better than others, and some decided to take the better ideas and combine them.
There would be a bit of protectionism involved as well. You don’t want someone buying an American product when they could buy manufactured right here in France, or vice versa. Travel was also a lot more difficult back then as well. Finally those that were travelling were not carrying a lot of electrical devices with them.
After these systems were developed, it’s much harder to go back and change them.
