What is the difference between AC and DC current?

Electricity is a type of energy that includes the movement of electrons along the conductor, such as a wire. Electron flow can occur in one direction or both directions along the wire. When electricity flows in one direction, it is referred to as direct current (DC). The alternating current (AC) is when electrons flow in both directions - one and then the other. Batteries produce direct current and electric power supply networks that provide electricity to households and other buildings, use AC current.

direct current

In nature, electricity occurs rarely, in some animals or with lightning. In finding the creation of electricity, scientists have found that electrical and magnetic fields are related. The magnetic field near the wire causes electrons to flow in one direction along the wire because they are repelled and attracted by the poles of the magnet. This is how the DC was born from the battery, which is a development that is primarily credited with America's work and the promotion of the inventor Thomas Edison during the 19th century.

AC current

on the conAnother scientist, a Serbian-American engineer Nikola Tesla, worked on the development of AC, as it could transfer different amounts of power. Instead of constantly applying magnetism along the wire, he used a magnet that turned. When the magnet was oriented in one direction, the electrons flowed towards the positive, but when the magnet orientation was reversed, the electrons also turned.

voltage

Another difference between AC and DC includes the amount of energy that everyone can carry. Each battery is designed to produce only one level of voltage, and that direct current voltage cannot travel very far until it starts losing energy. AC The voltage from the generator in the power plant can be hit up or down on the force of another mechanism called Transformer.

transformers

Transformers are used anywhere to increase or reduce the electrical voltage. For example, they are commonly seent on electric poles. Power plants produce electricity at very high voltage to travel long distances. However, the voltage must be reduced before electricity reaches home and other buildings that use it to power appliances, machines and other devices. AC can also be changed to a DC adapter, such as the type used to power the battery on a portable computer.
