Alternating current

Alternating current (AC) is a type of electrical current that changes direction periodically. Unlike direct current (DC), which flows in a single direction, AC alternates between positive and negative cycles. This makes AC more efficient for transmitting electricity over long distances, as it can easily be transformed to different voltages. Household outlets typically supply AC, making it the standard for powering home appliances, lighting, and other devices. The oscillation frequency is measured in hertz (Hz), with common frequencies being 50 Hz or 60 Hz, depending on the country.

    Alternating Current (AC) is a type of electrical current that periodically reverses direction. Unlike Direct Current (DC), where the flow of electricity is constant and unidirectional, AC changes its direction and voltage level over time. This is the standard form of electricity used in homes and businesses because it is more efficient for transmitting over long distances. AC power, typically generated by power plants, allows for the easy use of transformers to boost or reduce voltage levels, making it suitable for various applications, from powering appliances to lighting systems.
