Why do we use AC current?

The main factor that went into the choice of AC over DC was that AC is more efficient. Its ability to travel back and forth made gave it the ability to travel over longer distances. Thus making it able to power more homes. Today, in 2018, we’re still using AC electricity for most of our homes and businesses.

Why are AC generators used in power plants?

An alternating current (ac) generator is a device that produces a potential difference . A simple ac generator consists of a coil of wire rotating in a magnetic field. Cars use a type of ac generator called an alternator to keep the battery charged and to run the electrical system while the engine is working.

What are the commercial uses of electricity?

As the graph shows, on average, the biggest single uses of electricity in the commercial sector are lighting and heating, ventilation, and air conditioning. Electricity demand in the commercial sector tends to be highest during operating business hours; it decreases substantially on nights and weekends.

How is AC current generated?

Electric current is generated when a rotating loop of wire, known as an armature, is placed in a uniform magnetic field, or when a stationary armature is placed in a rotating magnetic field. In other words, each half of the armature periodically changes direction as the armature rotates.

Why is AC rather than DC current used in homes to supply electricity?

1. DC power is significantly more energy efficient than AC power. DC motors and appliances have higher efficiency and power to size characteristics. The greater efficiency resulting from recent developments in DC converter technology allows improvements in electricity delivery over long distances.

How electrical energy is generated transmitted and distributed?

Electricity is distributed via electric distribution substation. At the substation, the high voltage electricity from the high-voltage transmission lines is passed through step-down transformers that lower the voltage. The electricity is then transmitted to network of local electric distribution lines.

What does commercial electric mean?

A commercial electrician is a trained and licensed electrician who focuses on wiring and electrical systems in commercial buildings rather than residential buildings. These electricians work with bigger systems, in large buildings like shopping malls, office buildings, restaurants, government buildings and high rises.

What is commercial energy source?

The energy sources that are used to generate electricity and that are available in the marketplace with a specific price are known as commercial energy sources. The most commercialized forms of commercial energy sources are electricity, coal, and advanced petroleum products.
