Electrical Help at Your Fingertips

Direct current (DC) is an electric current that flows in one direction only. This means that the voltage of a DC signal does not change over time. DC signals are typically generated by batteries or solar cells.

Alternating current, on the other hand, is generated by power plants and flows through the power grid to homes and businesses. Read more..

An AC motor is an electric motor that uses alternating current (AC) instead of direct current (DC). AC motors are more efficient than DC motors and can be found in a variety of applications, including fans, pumps, and compressors. Read more..

Capacitors are used to store electricity. In contrast to the usefulness of resistors, capacitors do not dissipate energy in their optimal form. Read more..
 

Some common applications of direct current include:

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