AC power supplies are power supplies that use Alternating Current, which means that the current repeatedly changes its direction. AC power supplies are usually mains supplies as they are at a high voltage. Often filtering takes place between the mains supply and the device.
DC and AC
Power supplies can supply AC or DC current.
The "power supply" supplies power to a computer. A computer's power supply is a "switchmode power supply" responsible for converting the AC voltage from the wall into several DC output voltages.

Dc Power Supplies converts AC to DC Two Main types 1)Linear : A simple circuit with diodes and capacitors 2)Switched Mode: sampling technique is used to convert AC to DC.
The AC on an AC Cobra stands for Auto Carriers. AC Cars Group Ltd. was formally known as Auto Carriers Ltd. They are a British specialist automobile manufacturer.
ATX computer power supplies provide low volts DC of less than five volts. AT computer power supplies provide low DC only to five and twelve volts.
This statement is correct
Radios use DC power supplies to operate. If a radio is powered from a mains AC supply, a power supply circuit will convert the AC supply to DC. Therefore, a radio may have both a DC and an AC power input but ultimately, the internal circuitry will always use DC.
Batteries can provide both AC (alternating current) or DC (direct current) power, depending on the type of device they are connected to. However, most batteries themselves supply DC power. Devices that require AC power typically use an inverter to convert the battery's DC power into AC power.
All electricity supplies are a.c. D.C. is used, on occasions, for long-distance transmission (or undersea transmission) at very high voltages, but never for power supplies to homes or businesses.
