Anything that uses a battery is relying on a DC power source. Cell phones, laptops, cars, and cordless appliances like drills or even wine-bottle openers all use batteries as a source of direct current. If a device uses a battery as its’ power source, internally it is comprised of DC circuits.
DC, or direct current, is generated through a chemical reaction in sources like batteries, fuel cells, and solar cells. These devices convert chemical energy into electrical energy to produce DC voltage. In batteries specifically, the chemical reaction occurs between the anode and cathode, with the electrolyte facilitating this process.
