What is the difference between DC and AC?

In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes direction.

Also to know is, what does the word DC mean?

Washington was named after the first U.S. President, George Washington. The "D.C." stands for "District of Columbia", a special area created that is not a state.

What does DC output mean?

Usually an adapter is a device which is used to interface a DC operable device to an AC utility supply. Usually, small signal electronic gadgets like computers (both desktops and laptops), mobile phones, electronic trimmers etc require a much reduced DC input as compared to what is provided by the power grid.
