Answer 1

what r they? ??????????

Answer 2

DC- Direct current
AC- Alternating current

AC is a kind of current which alternates it direction after 'every very strict defined time period'.

The words between two quotation marks are very important.

DC current and AC current can interchange between one another using converters.

AC current is very widely used in many cases.

Nikola Tesla transformed the world of electricity.

So, DC always maintains its direction. But AC switches between + and - regularly.
