Difference between AC and DC in power sockets

Power socket in the AC refers to alternating current, DC refers to direct current, generally AC will be marked 250V10A, labeling allows the highest 250V voltage, 10A current. In the actual application of voltage and current values are best not to exceed the value to avoid fire and other hazards.

 

Alternating Current

AC stands for Alternating Current, in which the direction of the current changes periodically at a fixed frequency, and is generated mainly by devices such as power plants and transformers that convert mechanical energy into alternating current energy.

 

Direct Current

DC stands for Direct Current, where the direction of the current is always the same. DC can be generated by converting AC to DC using a rectifier, or directly by using a battery, for example.

In terms of transmission distance, AC has an advantage in long distance transmission. AC can be regulated by transformers and hence it can be transmitted at high voltages to minimize energy loss during transmission. However DC power experiences more energy losses when transmitted over long distances and more measures need to be taken to solve this problem.

Alternating current (AC) is the main form of public power grid, supplying electricity for domestic, commercial and industrial use. This type of power supply is used for most electrical equipment such as household appliances, lighting systems, and electric motors. DC power is more commonly used for electronic equipment, computers, battery-powered devices, chargers, and solar panels.
