Today 60Hz is used from Canada to Peru in America and also in other countries such as the Philippines, South Korea and parts of Japan. If there was too much frequency, then too little electricity would pass through the wire and the transformers would run less efficiently. If the frequency was less, then light bulbs were going to flicker. In the late 19th century, around 1890 or so, Nikola Tesla had decided that it would be appropriate to transport electricity at 60 Hertz. Alternating electricity is characterized by going back and forth a certain amount of times per second. Now, in most of the world 220V is used as for example most countries in Africa, in South America from Peru to Argentina, all Europe and most of Asia and Oceania. This value varies between 100 and 127V in reality. Countries such as the United States, Canada, Mexico, Ecuador, Japan, Taiwan, Colombia, Venezuela, among others, use 110V nominally. So, the first big difference in AC voltages was born. ![]() However, in Europe they decided that transporting electricity to residential areas at 220V would be more economical due to the reduction of electricity losses. ![]() In the United States of America it was chosen to have 110V so that it could work with the incandescent bulbs that Thomas Edison had already produced and therefore it was decided that it was going to be made the standard for residential areas. One of these is called the neutral and the other is called the line or phase. Voltage (V) indicates the strength, tension or potential difference that exists between the two wires that reach the connector of your house. World Map of Mains Voltages and Frequencies.
