An AC adapter or AC/DC adapter (also called a wall charger, power adapter, power brick, or wall wart) is a type of external power supply, often enclosed...

electric power requires high voltages. This reduces the losses produced by strong currents. Transmission lines use either alternating current (AC) or direct...

A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The resulting...
