What is AC (Alternating Current)?
AC (Alternating Current) is the standard form of electricity used in homes and businesses. Unlike Direct Current (DC), which flows in one direction, AC periodically changes direction, making it more efficient for transmitting electricity over long distances.
In HVAC systems, AC power is essential for operating air conditioners, heat pumps, and furnaces. Most household and commercial electrical appliances, including HVAC systems, lighting, and industrial equipment, rely on AC power.
Electricians work with AC power to install, repair, and maintain wiring, circuit breakers, and electrical panels. Understanding AC voltage, frequency (measured in Hertz), and phase configurations is crucial for ensuring safe and efficient electrical systems.
