Unlike Alternating Current (AC), which periodically changes direction, DC provides a constant voltage or current. It can be obtained from various sources such as batteries, solar cells, fuel cells, and modified alternators. DC power is known for its consistency in voltage delivery, making it a preferred choice for many electronic devices. These devices often rely on DC power sources like batteries.\n\nDC power can also be created from AC power by using a rectifier, which converts AC to DC. This conversion process allows electronic devices to convert the AC power available from outlets into the DC power they require. Additionally, a transformer may be used to adjust the voltage level of the DC power to match the requirements of the device.\n\nIt is important to note that not all electrical devices utilize DC power. Many household appliances, such as lamps, washing machines, and refrigerators, operate on AC power directly supplied from the power grid.\n\nIn summary, Direct Current (DC) in the lighting industry refers to a type of electrical current that flows in a single direction without changing polarity.
