Alternating Current

Alternating Current (AC)

Alternating current is an electric current whose magnitude changes with time continuously and which reverses its direction periodically. It is mathematically represented as
I=Io cosωt or I=Io sinωt

Advantages of AC over DC

  • Flexibility of converting from one value to other using transformer
  • Can be transmitted over long distances economically as well as without much power loss
Mean Value or Average value of AC (…
