Question

direct current and alternating current

Answer 1

hey...

AC or Alternating current doesn't have a constant magnetic flux thus the current changes continously ...2 slip rings are used and the magnets it self rotates..

DC or Direct current has constant magnetic flux thus the current doest change..only 1 slip ring is used and it is shared by both commutators..here slip rings rotate..

✨ Hello Mate✨
✔️Here is your answer ✔️
=========⤵️⤵️===========
$\color{Red}{Direct Current}$
➡️An electric current which always flows in the same direction is called direct current.
➡️The polarities of a direct current are fixed.

$\color{red}{Alternating current}$
➡️An electric current which changes its direction after a certain fixed interval of time is called alternating current.
➡️The positive and negative polarities are not fixed.

✌️Hope it helps you ✌️
