An AC circuit is an electrical circuit powered by an alternating current (AC) source, where the current periodically reverses direction. These circuits are fundamental in power distribution systems due to their ability to efficiently transmit electricity over long distances and their compatibility with transformers for voltage regulation.

Alternating current (AC) is an electric current that periodically reverses direction, in contrast to direct current (DC) which flows only in one direction. AC is the form of electrical power that is delivered to homes and businesses, and it is the form of electrical energy that consumers typically use when they plug appliances into a wall socket.

Voltage regulation refers to the ability of a power supply system to maintain a constant output voltage despite variations in input voltage or load conditions. It is crucial for ensuring the stability and efficiency of electrical and electronic systems, preventing damage and ensuring optimal performance.
