What is dc power supply definition.

Low dc voltages are needed to operate ics and transistors. Direct current may flow through a conductor such as a wire but can also flow through semiconductors insulators or even through a vacuum as in electron or ion beams. A power supply is a hardware component that supplies power to an electrical device. A dc power supply is one that supplies a constant dc voltage to its load.

Direct current dc is the one directional or unidirectional flow of electric charge. Direct current dc power refers to the unidirectional flow of electrons and is the form of power that is most commonly produced by sources such as solar cells and batteries. A power supply delivers electricity to one or more electrical loads. The device traditionally converts one form of electricity to the other.

A dc connector or dc plug for one common type of connector is an electrical connector for supplying direct current dc power. Compared to domestic ac power plugs and sockets dc connectors have many more standard types that are not interchangeable. A dc power supply is a device that supplies electric energy of fixed polarity either positive or negative. Dc in this context means direct current direct current is an alternative to alternating current frequently shortened to ac power supplies take energy from a power input and deliver it to a power output.

It receives power from an electrical outlet and converts the current from ac alternating current to dc direct current which is what the computer requires. Some of the most well known devices convert from ac to dc power but you also have the option of dc to dc power supplies. A power supply is an electronic circuit designed to provide various ac and dc voltages for equipment operation. Depending on its design a dc power supply may be powered from a dc source or from an ac source such as the power mains.

A handheld video game which is charged with an ac dc power supply. Power supplies are designed to convert a power source into the type of electricity you need. The intensity of the current can vary with time but the general direction of movement stays the same at all times. Power supplies can be found on many things such as for television sets computers video game consoles and even home phones.

As an adjective the term dc is used in reference to voltage whose polarity never reverses.
