## Definition

AC refers to Alternating Current and DC refers to Direct Current. An alternating current (AC) refers to an electrical current whose magnitude and direction vary periodically, as opposed to direct current (DC). The direction of Direct Current (DC) always remains constant. AC and DC are electric supply current adaptors. With AC it is possible to build electric generators, motors and power distribution systems that are far more efficient than DC, and so we find AC used predominately across the world in high power applications.

Alternating current (AC) is the most efficient way to deliver electrical power. However, most electronic devices need direct current (DC) to function. For this reason, AC to DC converters are either a part of devices themselves or as part of their power cords. Direct current (DC) is used to charge batteries, and also used in nearly all electronic systems as the power supply. Electric power that is being distributed all over is nearly all Alternating Current (AC) today.

E.g. – If you have built a device you wish to power from an AC outlet, you must add an AC to DC converter ## Formula

The AC-DC Converter is used to calculate and convert the electric currents from Alternating Current (AC) to Direct Current (DC) or DC to AC by applying the formula.

AC(volts) = DC(volts) / 0.636

where

AC- Alternating Current

DC – Direct Current

Example:

Convert the given value of Direct Current (DC) to Alternating Current (AC) if DC Current = 10 volts ?

Sol. :

AC = DC / 0.636

AC = 10(v) / 0.636

AC = 15.723 volts

AC Current = 15.723 volts

## Units

The standard unit of measurement for AC/DC is Volts

One volt is equal to performing one joule of work to move or separate one coulomb of electrons.

If the wattage and amperage of the circuit are known, then voltage equals wattage divided by amperage (1volt = 1watt /1 amp).
