What does DC and AC stand for?

in Electrical Engineering

1 Answer

DC stands for Direct Current, and AC stands for Alternating Current.

Direct Current (DC): In DC, the electric charge flows in one direction only. It’s a constant flow of electricity, like what you get from a battery or a solar panel.

Alternating Current (AC): In AC, the electric charge changes direction periodically. The current alternates back and forth. This is the type of electricity that comes from power outlets in your home and is used for most household appliances.

So, the main difference is that DC flows in one direction, while AC switches direction periodically.
