What is characteristics of alternating current?

Answer 1

One of the characteristics of the current electricity is that AC indicates alternating current whereas the DC indicates direct current. Another characteristic is that they function between 1 and 3 convectional phases.

Answer 2

It has the ability to be transmitted over longer distances than Direct Current, due to the fact that you can use Transformers to step the voltage way up or down.

Strictly speaking, it's the the fact that transmission losses are lower for higher voltages (higher voltage = less current for the same power) that makes this so desirable. It's possible to step DC voltages up or down, but it's relatively complicated compared to the "wind a bunch of wire around an iron core" of a transformer.

Answer 3

The basic idea is that the voltage - and therefore also the current - changes direction continuously. For example, if the frequency is 50 Hz, that means a full cycle is 1/50 of a second. In part of one such cycle, the current will go in one direction; in another part of the cycle, it will move in the opposite direction.

Answer 4

AC is generated by a revolving motor which results in a sine wave which travels from positive to negative as the motor completes one revolution of 360 degrees. This development in electrical power generation by Nikola Tesla, and bought by the Westinghouse company, is what soundly beat Thomas Edison's Direct Current (DC) electricity generation from Edison Electric. DC does not have the capacity for the long range transmission of electricity that AC does. It is said that so many wires were strung around New York before Tesla revolutionized the industry with AC that they blocked out sunlight.

Direct current is what batteries generate, a voltage and current that travels from positive to negative. Again, it cannot travel very far. However, even though AC is the predominant means of delivering power to homes and businesses, most items that we use in our daily lives are actually DC powered, even if they're plugged into an AC outlet. This is due to what's known as a Transformer inside the device that transforms / converts the incoming AC voltage to a lower DC voltage required to power the device.

All electronic devices have DC power supplies within them.
