WHY AC SYSTEMS ARE PREFERRED OVER DC? | Why is AC power used instead of DC?

AC power is used instead of DC

We (Usually all over the world), In all the countries, use AC voltage for consuming and for using electricity. Why not DC voltages?
It may ask you in an interview so it’s better to know it first.
There are some factors for using AC rather than DC.

  • From the powerhouse/power plant, we produce AC voltages so it’s better to use AC rather than convert it from AC to DC (because there is extra no benefit to using DC). We need to change transformers, breakers, and other devices that we are using at the powerhouse.
  • It is easy to maintain AC voltages and step up & step down AC voltages as compared to DC.
  • The cost of power-plant is much lower than the DC generation plant (transformers, circuit breakers, etc).
