0416 501 728Alternating Current (AC) is a type of electrical current in which the flow of electrons periodically reverses direction. Unlike Direct Current (DC), where electrons flow continuously in one direction, AC’s voltage oscillates in a sinusoidal pattern, typically described by its frequency (measured in hertz, Hz) and amplitude. In most regions, AC power is delivered at either 50 Hz or 60 Hz.
AC is widely used for transmitting electricity over long distances due to its efficiency. It can be easily transformed to higher or lower voltages using transformers, minimizing energy losses during distribution. This capability has made AC the standard for residential, commercial, and industrial power systems.
The alternating nature of AC makes it compatible with many types of electrical devices, including motors, heating systems, and lighting. It also supports efficient generation methods, such as using rotating machines in power plants.
In homes and businesses, the standard voltage and frequency of AC supply depend on the region, such as 230V at 50Hz in Europe and 120V at 60Hz in North America. Modern electrical systems rely heavily on AC due to its flexibility, safety in transmission, and cost-effectiveness.
