What is alternating current?

Alternating current can be defined as a current that changes its magnitude and polarity at regular interval of time. It other words it can also be said as an electrical current that repeatedly changes or reverses its direction opposite to that of Direct Current or DC which always flows in a single direction. Alternating current can be identified in waveform called a sine wave. These curved lines depict the electric cycles and are measured per second. The unit to measure alternating current or AC is Hertz or Hz. The first test on electric current was done the principles laid by Michael Faraday in 1832 using a Dynamo Electric Generator.

Applications of Alternating current

  • Used in all household appliances
