Electrical Help at Your Fingertips

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..

Rectifiers work by allowing only half of the AC cycle to pass through them. During the positive half-cycle, the rectifier allows electrons to flow from the negative terminal to the positive terminal. Read more..

Alternating current (AC) is an electric current that reverses direction periodically. This means that the voltage of an AC signal also reverses direction periodically.

The frequency of an AC signal is the number of times per second that the current or voltage reverses direction. Read more..

Some common applications of direct current include:

1. powering electronic devices
2. charging batteries
3. operating electric motors
4. welding metals
