Why are electric plugs different in different countries?
Engineers developed the idea of a ground pin to make plugs safer in the 1920s. Many countries adopted these grounded plugs immediately, but they didn’t always make them the rule. So because different countries adopted innovations like these at different times, the plugs that they used changed throughout the years.
Why different countries have different standard voltages?
Companies in Europe realized that supplying power at 220 volts instead of 110 volts would be cheaper. At a higher voltage, electric companies can deliver the same power with less current – picture a narrow stream flowing quickly compared to a wider stream flowing slowly. And less current allows for thinner wires.
Why are American and European plugs different?
The standard in North America is 110 to 120 volts, while the European standard is 220-240 volts. This necessitates a difference in the way outlets are constructed in Europe and in North America. The standard in North America is 60Hz, while the European standard is 50Hz.
What plugs are used in different countries?
Everything you need to know about your international travel plug adapter

| American Samoa | A, B, F, I | 120 V |
| Andorra | C, F | 230 V |
| Angola | C | 220 V |
Why is electric different in Europe?
Europe’s electrical system is different from ours in two ways: the voltage of the current and the shape of the plug. Some older appliances have a voltage switch marked 110 (US) and 220 (Europe) — switch it to 220 as you pack.
Why other countries use 110 volts and other uses 220 volts?
Because they use a low frequency, so they have to spend more money solving the power loss and high heating problems. Until the 1950s after World War II, Europe still use 110V, and then they changed to 220V to improve power transmission efficiency.
Why do other countries use 220 volts?
Cost was the main reason Europe went with 220 volts (now 230). Counterintuitively, higher voltages allow the use of thinner wire, meaning less copper in the early days of power lines. Power companies could save money on wire by using 220 volts rather than 110.
How many different plugs are there in the world?
Plug & socket types around the world There are currently 15 types of domestic electrical outlet plugs in use worldwide, each of which has been assigned a letter by the US Department of Commerce International Trade Administration (ITA), starting with A and moving through the alphabet.

Are plugs different in Europe?
All of Europe operates on the same 2 round pronged outlets except for the UK and Ireland that operates on its own unique 3 flat rectangle pronged outlets. If you are travelling through the UK or Ireland (including London) you will need a UK and Ireland power point adapter.
