Electrical Help at Your Fingertips

A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The process is known as rectification. Read more..

AFCIs work by sensing when an arc fault is about to occur and then interrupting the flow of electricity before the arc can form. Read more..

AC motors are more efficient than DC motors and can operate at higher speeds. Additionally, AC motors are less likely to overheat than DC motors and can be used in a variety of applications. Read more..

Alternating current can be dangerous if not used properly. For example, touching a live wire carrying AC can result in electrocution. AC can cause interference in electronic devices, which can lead to data loss or corruption. Read more..
