AC and DC electricity
AC (Alternating Current): The flow of electricity in which the direction of current changes periodically.
DC (Direct Current): The flow of electricity in which the direction of current remains constant.

Circuit
A closed path that allows current to flow.
Series and parallel circuits
Series circuits have current flow in the same direction, while parallel circuits have current flow in opposite directions.
Over time, Electrical Engineering and Automation has evolved to include a wide range of sub-fields, including power engineering, control systems, robotics, and more.
Computer control systems can be used for a wide range of applications, including industrial manufacturing, process control, aviation, and more.
