WHAT'S THE DIFFERENCE?

AC stands for Alternating Current. It refers to the supply and transmission of electrical energy in which the direction of electric charge changes 50 times a second. In AC power, the voltage and current alternate in direction and magnitude, typically following a sinusoidal waveform. AC generators, such as alternators, convert mechanical energy into electrical energy. The most common frequency for AC power is 50 or 60 Hz (hertz), indicating the number of complete cycles per second. AC power has several advantages over DC power. It allows for easy voltage transformation using transformers, which traditionally enabled efficient transmission of electricity over long distances. AC is also suitable for powering a wide range of electrical devices, as it can be easily converted to different voltages using transformers and stepped down using power supplies. AC power is used for residential and commercial electrical systems, providing electricity to homes, offices, and industries. It is also the standard form of power delivered through power grids and is commonly used to operate appliances, lighting systems, motors, and other large electronic devices.
