How does alternating current differ from direct current?

Answer 1

Direct current (DC) is a type of electric current that only flows in one direction; alternating current (AC) flows in both directions, forward and backward.

Most homes in the world are powered by alternating current (AC), which is used in the production and transportation of electricity.

Because direct current (DC) can only flow in one direction, it is primarily used in batteries, which require replacement when the current runs out.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
