What is the difference between AC and DC electricity?

AC and DC electricity are two types of electrical current. AC stands for Alternating Current and DC stands for Direct Current. The main difference between the two is the direction in which the current flows.

DC current flows in one direction only, while AC current changes direction periodically. AC current is used in most household electrical devices, as it can be transmitted over long distances with minimal power loss. DC current, on the other hand, is used in batteries and electronic devices, such as smartphones and laptops.

Another important difference between AC and DC is their voltage. AC voltage can easily be changed with the use of a transformer, while DC voltage remains constant. AC voltage is usually much higher than DC voltage, which is why it is used for power transmission over long distances. DC voltage, on the other hand, is often used for low-voltage applications such as electronics and battery-powered devices.
