DC Full form

Full form of DC

Direct current is the full form of DC. Direct current is the unidirectional flow of an electric charge. Direct current may flow through conductors like wire, but it can also flow via the semiconductors or vacuum. The electric current flows constantly, distinguishing it from alternating current (AC).

Examples of direct current

The primary use of DC is for the power supply and to charge the batteries for electrical equipment. The mix of plus & minus signs, a dotted line, or a straight line is available in DC.

Examples- Mobile phone batteries, Flashlights, electric vehicles, and a flat-screen TV.

How can we convert AC to DC and DC to AC?

  • A rectifier can convert the alternating (AC) into a direct current.
  • The direct current (DC) can be converted into an alternating current using an inverter.

Benefits of DC

  • The electrical device is more powerful when charged from DC.
  • Less chance of electrical shocks if the voltage is less than 48V
  • The DC transmission line can transfer more power over long distances with less loss of electricity. It also enhances performance and decreases the cost of transmission.
  • Compared to AC lines, DC transmission lines need less ground and narrower structural support.

Uses of Direct Current

  • DC is used for batteries used in automobiles
  • To charge a battery
  • To run a DC motor
  • To transmit the large amounts of a power from remote generation sites
  • To melt down aluminium and other electrochemical components

Disadvantages of DC

  • One of the most significant disadvantages is that the energy loss is very high at a low voltage.
  • It is challenging to convert DC to AC. However, it is comparatively easy to convert AC to DC.
