Europe and most other countries in the world use a voltage which is twice that of the US. It is between and volts, whereas in Japan and in most of the Americas the voltage is between and volts. The system of three-phase alternating current electrical generation and distribution was invented by a nineteenth century creative genius named Nikola Tesla first picture.
He made many careful calculations and measurements and found out that titleist ts2 fairway wood review Hz Hertz, cycles per second was the best frequency for alternating current AC power generating.
He preferred volts, which put him at odds with Thomas Edison second picturewhose direct current DC systems were volts. When the German company AEG built one of the first European generating facilities, its engineers decided to fix the frequency at 50 Hz, because the number 60 did not fit the metric standard unit sequence 1, 2, 5.
At that time, AEG had a virtual monopoly and their standard spread to the rest of the continent. In Britain, differing frequencies proliferated, and only after World War II the cycle standard was established. Originally Europe was V too, just like Japan and the US today, but it was deemed necessary to increase voltage to get more power with fewer losses and less voltage drop from the same copper wire diameter. At the time the US also wanted to change but because of the cost involved to replace all electric appliances, they decided not to.
At the time 50ss the average US household already had a fridge, a washing-machine, etc.
Plug, socket & voltage by country
The result was that throughout the 20th century, the US had to cope with problems such as light bulbs that burnt out rather quickly when they were close to the transformer too high a voltageor just the other way round: not enough voltage at the end of the line to volt spread! The common neutral wire is connected at the centre point of the split volts on the main panel. The full volts is used for powerful appliances such as ovens and clothes dryers. Mind, Americans who have European equipment should not connect it to these outlets, since the phasing is wrong.
Below is a map that shows the domestic voltage and frequency used in every country of the world. Dark blue coloured countries use V. The electrical network in red countries operates at V. Keep in mind that this map is only a general overview. Sometimes there can be voltage differences within one and the same country.

Type G. Type H. Type I.Many travelers to Europe have had difficulties with their electronics, because European and American power systems are run differently.
As a result, appliances in these nations are designed to connect to a specific type of power source, and using American devices in European outlets and vice versa can result in havoc. Many nations also use different plugs, and a number of plug adapter kits are available for connecting to foreign plugs. However, use of these plugs without a transformer or voltage converter can result in fireworks.
The voltage in Europe is twice that of the voltage in the United States, and while many electronics are designed to adapt to voltage changes, it is crucial to check.
If the device is not capable of handling volts of electricity, it will fail. In addition, some electrical devices cannot handle the lower 50 hertz cycle found in much of the world, and may experience difficulties. To see if a voltage converter is needed, look at the informational panel on the back of the electrical device in question.
Many manufacturers design equipment with varying voltages in mind, and may list an ability to handle input ranging from volts, indicating that it will work in Europe and the United States. If this is the case, a voltage converter is necessary. If this is the case, look at the wattage requirement of the device, which should also be listed.
When buying a voltage converter, be certain to get one with a wattage which has a higher rating than the device you are plugging in, to prevent electrical malfunction. Travelers are cautioned to be especially cautious with hair dryers, which have very high wattage requirements. In general, it is safer to purchase a hair dryer in the country where it will be used, or to purchase a voltage converter which can handle at least watts to avoid damage to the hair dryer, operator, and electrical system it is plugged into.

It is the form of electrical power that is delivered to homes and businesses, and it is the form of electrical power that consumers use when they plug items such as domestic appliances, televisions and electric lamps into wall outlets.
What are the Electrical Voltage Differences Between the US and Europe?
The two principal properties of the electric power supply, voltage and frequencydiffer between regions. This is a concern to travellers, since portable appliances designed for one voltage and frequency combination may not operate with, or may even be destroyed by another.
The use of different and incompatible plugs and sockets in different regions and countries provides some protection from accidental use of appliances with incompatible voltage and frequency requirements.
In the US, mains electric power is referred to by several names including "utility power", "household power", "household electricity", "house current", "powerline", "domestic power", "wall power", "line power", "AC power", "city power", "street power". In the UK, mains electric power is generally referred to as "the mains".240V is the Standard US Household Voltage (Kinda.)
More than half of power in Canada is hydroelectricityand mains electricity is often referred to there as "hydro". For a list of voltages, frequencies, and wall plugs by country, see Mains electricity by country.
Worldwide, many different mains power systems are found for the operation of household and light commercial electrical appliances and lighting. The different systems are primarily characterized by their. All these parameters vary among regions.
The voltages are generally in the range — V always expressed as root-mean-square voltage. Single-phase or three-phase power is most commonly used today, although two-phase systems were used early in the 20th century.
Foreign enclaves, such as large industrial plants or overseas military bases, may have a different standard voltage or frequency from the surrounding areas. Some city areas may use standards different from that of the surrounding countryside e. Regions in an effective state of anarchy may have no central electrical authority, with electric power provided by incompatible private sources.
Direct current DC has been almost completely displaced by alternating current AC in public power systems, but DC was used especially in some city areas to the end of the 20th century. Industrial plants with three-phase power will have different, higher voltages installed for large equipment and different sockets and plugsbut the common voltages listed here would still be found for lighting and portable equipment.
Electricity is used for lighting, heating, cooling, electric motors and electronic equipment. Estimated US residential electricity consumption by end use, for the year . The other categories are typically AC applications and usually have much more restricted input ranges. Any current perceived weakness is generally a result of cost reduction and market forces rather than any fundamental technical difficulties.
Where opportunities do exist they are often for specific parts of the overall load and often small parts in terms of total demand.
In many countries, household power is single-phase electric powerwith two or three wired contacts at each outlet. Neutral and line wires carry current and are defined as live parts. Various earthing systems are used to ensure that the ground and neutral wires have zero voltage with respect to earth, to prevent shocks when touching grounded electrical equipment.To keep up to date on the latest News and Views on the state of global electricity supplies….

Check if you need a power plug adapter or voltage converter for the power sockets outlets used in the United States of America. Below you find pictures of the applied power sockets and corresponding plugs. And we provide more information about the voltage and frequency. Check out the following pictures. Your power plugs fit. We recommend you to pack a 3 to 2 prong adapter in case type B sockets are not available.
We don't sell power plug adapters.
We refer you to Amazon, where you will find a great selection of travel adapters. To be sure, check the label on the appliance. Some appliances never need a converter. Would you like to add information to this page?
For industrial machinery, see industrial and multiphase power plugs and sockets. Some countries have more than one voltage available. Often different sockets are mandated for different voltage or current levels.
Voltage, frequency, and plug type vary, but large regions may use common standards. Physical compatibility of receptacles may not ensure compatibility of voltage, frequency, or connection to earth groundincluding plugs and cords. In some areas, older standards may still exist.
Foreign enclaves, extraterritorial government installations, or buildings frequented by tourists may support plugs not otherwise used in a country, for the convenience of travellers. The International Electrotechnical Commission publishes a web microsite World Plugs  which provides the main source for this page, except where other sources are indicated.
World Plugs includes some history, a description of plug types, and a list of countries giving the type s used and the mains voltage and frequency. Although useful for quick reference, especially for travellers, IEC World Plugs may not be regarded as totally accurate, as illustrated by the examples in the plugs section below, and errors may exist, such as Indonesia being listed as using both V and V when the Indonesian Standard SPLN 1  clearly states the voltage as V, and the official travel website says "electric power supply is volts in all regions.
Voltages in this article are the nominal single-phase supply voltages, or split-phase supply voltages. Three-phase and industrial loads may have other voltages. The system of plug types using a single letter from A to N used here is from World Plugswhich defines the plug type letters in terms of a general description, without making reference to specific standards. The Brazilian version is non-compliant with the IEC standard.
So-called "universal socket" which meets no standard  but accepts a number of different plug types criticized as unsafe. From Wikipedia, the free encyclopedia. Wikimedia list article. For further information on each plug and discussion on the different voltages and frequencies used, see AC power plugs and sockets and Mains electricity. Main article: AC power plugs and sockets. Retrieved on Archived from the original on 4 December Retrieved 1 December Ministry of Tourism, Republic of Indonesia.
Archived from the original on 23 April Retrieved 23 May The table shows that in most countries the mains supply is between and volts 50 or 60 Hz ; countries that operate on volts are greatly outnumbered. The list also reveals that types A and C are the most frequently used electric plugs worldwide.
If you take a scroll down the page, you will notice that most countries have a well-defined plug and voltage standard. Many Latin-American, African and Asian countries, however, use a motley collection of — often incompatible — plugs and sometimes also the voltage differs from region to region. Obviously, this makes it very hard for travellers to assess what kind of plug adapter or transformer they will need for their trip.
