Electrical Help at Your Fingertips

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..

Ohm’s law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. In other words, the higher the voltage, the higher the current. Read more..

Ohm’s law is used in many branches of physics, including electricity, magnetism, and optics. It can be used to design electrical circuits, calculate power dissipation in electronic devices, and troubleshoot electrical problems. 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..
