science physics# How do you convert DC current to AC current?

Last Updated: 16th June, 2020

**power**inverter, or inverter, is a

**power**electronic device or circuitry that changes

**directcurrent**(

**DC**) to

**alternating current**(

**AC**).The input

**voltage**, output

**voltage**and frequency, andoverall

**power**handling depend on the design of the specificdeviceor circuitry.

Correspondingly, how do you calculate DC to AC?

Historically there was interest in relating thepowersourcing capabilities of **AC** to **DC**.To**calculate** the power through a load powered by **DC**allyou need to do is multiply the power by the current: Volts *Amps =Power. The problem in doing this with **AC** is that thevoltageis continuously changing.

Also, why do we convert DC to AC? **We** need to **convert AC** to **DC**becauseof below facts: **AC** signals can not be stored and**DC**power or signals can be stored.Thus,to store theelectrical energy**we** need to **convert** it into**DC**. **AC** canbe transported over long distances becauseof it's frequency and**dc** can not be transported as **dc**has zerofrequency.

are AC and DC amps the same?

**DC Amps** and **AC amps** are theexact**same** thing, they are the measurement of electrons pastagiven point, the difference is that the electrons of **AC**goback and forth (alternating) and **DC** go only in onedirection(direct).

Is AC power equal to DC power?

Summary: Watts out **DC** = 75% to 90% of**AC**Watts in, in most cases. See below: At 100% efficiency ADCWattsout = **AC** Watts in. Energy is 'conserved" and energy =Wattsx time.
