What is AC/DC electrical systems?

AC/DC electrical systems refer to the use of both alternating current (AC) and direct current (DC) electricity in various applications. AC is characterized by its periodic reversal of current direction and is commonly used for long-distance power transmission and powering most household appliances. DC, on the other hand, flows in one direction and is typical for batteries, electronic devices, and some specialized industrial equipment. Many systems involve converting AC to DC (e.g., phone chargers) or DC to AC (e.g., inverters for solar power) to efficiently meet the specific power requirements of different devices and applications. Modern power grids and electronic devices commonly use a combination of both AC and DC, where AC is used for transmission and DC for local power conversion and use within devices.
