The HVDC Cross-Channel (French: Interconnexion France Angleterre IFA 2000) is the 73-kilometre-long (45 mi) high-voltage direct current (HVDC) interconnector that has operated since 1986 under the English Channel between the continental European grid at Bonningues-lès-Calais and the British electricity grid at Sellindge.
Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...
Mains electricity by country includes a list of countries and territories, with the plugs, voltages and frequencies they commonly use for providing electrical power to low voltage appliances, equipment, and lighting typically found in homes and offices. (For industrial machinery, see industrial and multiphase power plugs and sockets.) Some ...
The 51-kilometre (32-mile) DC cable runs via the Channel Tunnel between HVDC converter stations at Peuplingues in France and Folkestone in the UK, with an additional 14.5 km (9.0 mi) of underground AC cable on the English side to Sellindge substation, and 3.5 km (2.2 mi) on the French side to Les Mandarins substation, [3] to link the converter stations to the existing transmission networks.
A "power cube"-type AC adapter. An AC-to-DC power supply adapts electricity from household mains voltage (either 120 or 230 volts AC) to low-voltage DC suitable for powering consumer electronics. Small, detached power supplies for consumer electronics are called AC adapters, or variously power bricks, wall warts, or chargers.
Wiring is an open-source electronics prototyping platform composed of a programming language, an integrated development environment (IDE), and a single-board microcontroller. It was developed starting in 2003 by Hernando Barragán .

An AC adapter or AC/DC adapter (also called a wall charger, power adapter, power brick, or wall wart) [1] is a type of external power supply, often enclosed in a case similar to an AC plug. [2] AC adapters deliver electric power to devices that lack internal components to draw voltage and power from mains power themselves.
