What Is AC?

AC is a common form of electric power. AC power is delivered directly from the power grid through electrical outlets. This kind of power is known for its even voltage and smooth flow. It is used for many household appliances and electrical devices. While DC power is more efficient than AC, there are some instances where AC power is preferred.

In the mid-1800s, AC was still relatively new. Thomas Edison lobbied state legislatures and spread disinformation to discourage its use. He even directed technicians to publicly electrocute animals with AC. This was done to prove that AC was more dangerous than DC. Edison employees also designed the first electric chair in the United States using AC.

AC voltage is a difference in potential between the positive and negative terminals. It takes the shape of a sine wave as it starts at 0V, rises to a peak, and then drops back down to a negative peak. The difference is expressed in root-mean-square (RMS) values.

One of the main components of an AC motor is the stator. This is the part that converts a magnetic field into an electromagnet. There are several types of AC motors, but one of the most common is the squirrel cage type. It has a steel shaft that is pressed into the center of the assembly.https://www.youtube.com/embed/v2AC41dglnM
