ELECTRICAL ENGINEERING

Alternating Current (A.C) : The term alternating  indicates , that the current value changes instant to instant. Alternating current is simply the movement of electrical charge through a medium that changes direction periodically.

This is in the form of waves. One complete wave consists of half negative and half positive wave and is called one cycle.

Advantages of Alternating Current (A.C)

  • Voltage can be dropped or raised with the help of transformers.
  • Saving in Copper wire in transmission.
  • It loses far less power over long electrical lines.
  • This can be produced to maximum voltage i.e. 6600 volts
  • Its mechanism is simple and cheap.
  • Output is more due to availability of more than one phase.

Disadvantages of Alternating Current (A.C)

  • Due to thin wire in A.C., the voltage drop is more.
  • It cannot be used for electroplating and in charging secondary cells.
  • A single phase motor is not self-starter.
  • The speed of motors run by it is difficult to change.
  • There is danger to security due to high voltage.
