Electrical outlets are openings connected to a power source for powering devices. Different countries have different standards and voltages, making some sockets incompatible. International adapters can help, but voltage converters may also be necessary to prevent equipment damage.
An electrical outlet is an opening or series of openings connected to a wired power source intended to power electrical equipment and components. It is one of the most commonly used items in a home or building and can be found almost universally, although many countries have different standards or voltages. Consequently, not all sockets, or the components for which they are intended, are compatible with each other.
Most home electronics are powered by a cord plugged into the outlet. The component plug transfers power from the electrical outlet to the device that requires it. Another wire then returns the electricity to its original location. For simplification, in a domestic environment, this is the electrical panel. Because of this round-trip path, it is often called an electrical circuit.
In the United States, the standard electrical outlet has a pair of parallel vertical slots less than 1 inch (2.5 cm) apart, plus a round opening centered below the vertical slots. The round opening is for the ground, which offers some security. Voltage in the United States is usually 120 volts. In addition to the United States, this standard plug is often used in eastern parts of South America, some Caribbean countries, and some Middle Eastern countries.
In most of Europe, the standard plug has two openings spaced horizontally less than 1 inch (2.5 cm) apart. Its voltage is usually between 220 and 230 volts, but can vary according to location. This type of plug is more commonly known as a Europlug, due to its use in that part of the world. It is also the most used type internationally.
In the UK, the mains socket plug has two horizontal slots at the bottom and one vertical slot slightly above the horizontal ones. The slits together form a triangular shape. The plug can also be found in other parts of the world, such as Latin America and Africa. Its most common voltage is 230 volts.
For travellers, international adapters can allow you to connect devices made in one country to outlets in others. Just because someone might be able to plug an electronic component into an international outlet doesn’t mean they should, however. If the component is not made for a higher voltage, the person will also need a converter to step down the voltage. Otherwise, the electricity will overload the equipment and render it unusable.
