Alternating Current (AC) is a type of electrical current in which the flow of electric charge periodically reverses direction. It is the standard form of electricity used in homes, schools, and industries because it can be efficiently transmitted over long distances. AC is commonly generated by power plants and is essential for operating everyday devices such as lights, fans, computers, and household appliances. Its ability to change voltage levels easily using transformers makes it practical, economical, and widely used around the world.
