When electric power was first being developed and used, it was unclear whether AC or DC would become the dominant way.

The short answer is, “both”. The U.S. electric grid and the power flowing into your home are AC. As a result, most plug-in home appliances — refrigerators, electric ovens, microwaves, and so on — run on AC power Batteries, however, use direct current: they.

Solar panels produce direct current: the sun shining on the panels stimulates the flow of electrons, creating current. Because these.
