Hint: A continuous flow of electric charge with no change in direction. In direct current, the flow of electric current doesn’t change its direction periodically. DC is unable to travel over great distances. It loses its ability to generate electricity.
Complete answer:
Direct current (DC) is a one-way electric charge flow. A good example of DC power is an electrochemical cell. Direct current can flow via a wire, but it can also flow through semiconductors, insulators, or even a vacuum, as in electron or ion beams. Electric current is distinguished from alternating current by the fact that it flows in a consistent direction (AC). Galvanic current was once a word for this type of current.
When modifying current or voltage, the abbreviations AC and DC are frequently used to signify merely alternating and direct.
A rectifier, which incorporates electrical elements (typically) or electromechanical devices (historically) that allow current to flow only in one direction, can convert alternating current to direct current. An inverter is used to convert direct current to alternating current.
Direct current has a wide range of applications, from battery charging to huge power sources for electronic systems, motors, and other devices. In the smelting of aluminium and other electrochemical processes, enormous amounts of direct-current electrical energy are used. Some railways, particularly in metropolitan areas, use it as well. To transmit huge amounts of power from faraway generation sites or to connect alternating current power networks, high-voltage direct current is employed.
Examples of Direct current:-
$*$ Mobile battery gives DC
$*$ Laptop battery gives DC
$*$ Solar panels provide DC
$*$ Power Banks provide DC
Note:
A good example of a DC source is a battery. The electrical energy generated in a battery from the chemical energy contained in the battery. When a battery is connected in a circuit, it produces a continual flow of charge from the battery's negative to positive terminals.
