Many Latin-American, African and Asian countries are still in the same situation that Brazil used to be in.
What is the standard electrical plug in America?

Does America have different plugs?
USA travel adaptors: which type do I need? For USA there are two associated plug types, types A and B. Plug type A is the plug which has two flat parallel pins and plug type B is the plug which has two flat parallel pins and a grounding pin. USA operates on a 120V supply voltage and 60Hz.
Why are American plugs so dangerous?
As for US plugs only handling 120 volts at 10 amps, much over 50 – 60 milliamps is enough to cross the skin barrier and 10 amps AC will kill you as stone dead as 13 if it gets you the right way.
What country has the safest plugs?
British
The fuse and sturdy construction prove the British plug is very clearly the safest in the world. But it’s better than that, because the sockets also feature shutters that prevent children from inserting paperclips and getting a nasty shock.
Why do American plugs have no Earth?
They are designed to only be used in dry environments. Things with two pins are not earthed, they have extra insulation to prevent you from being shocked. Not all appliances need Earth. Appliances which need earth(eg washer driers etc.,) do have earth pin.
Why does America use 120V?
The choice of 120V was to compensate for IR drop. The reason for 220-240 was that with AC distribution, this became a convenient voltage level to deliver to homes.
Why do American plugs not have switches?
Originally Answered: Why do power outlets in America not have switches? The reason why is because the electrical safety codes in the U.S. do not require common power outlets to have ON/OFF switches. They are not necessary from a safety standpoint due to the design and use of the circuit.
Why is the British plug so safe?
Prong Design: Like standard U.S. grounded plugs, the U.K. wall plug has three prongs. Although the built-in fuse adds bulk to the U.K. plug design, it’s also safer: In case of an unexpected electrical surge, the fuse simply blows and the electricity shuts off, preventing fires, electrocutions, and other accidents.

What’s the difference between US and Japanese power plugs?
The Japanese plug has two identical flat prongs, whereas the US plug has one prong that is slightly larger, it is not a problem to use Japanese plugs in the US, however the opposite doesn’t always work. The holes at the tip of the prongs on type A (and B) plugs are there to prevent the plug slipping out from the socket, pretty nifty!
How big is the plug on a worldstandard?
The centre-to-centre distance between the grounding pin and the middle of the imaginary line connecting the two power blades is 11.9 mm. The plug is rated at 15 amps.

Is it dangerous to use a type a power plug?
Type A and B sockets are potentially dangerous, since the distance between the receptacle and a partially pulled-out plug is big enough to touch the pins with your fingers or with a metal object such as a teaspoon.
