AC and DC electrical current
AC and DC electrical current AC and DC are two types of electrical current that are used to power various electrical devices and systems. The terms AC and DC stand for alternating current and direct current, respectively. These two types of currents differ in their properties, applications, and advantages and disadvantages. AC: AC is a type of electrical current that changes direction periodically, meaning that the direction of the current flow alternates back and forth at a certain frequency. AC is commonly used in power generation, transmission, and distribution systems, as well as in most household appliances, such as fans, air conditioners, and refrigerators. AC is also used in industrial equipment, motors, and machinery. The voltage of AC can be easily transformed to higher or lower levels using transformers, which makes it ideal for long-distance transmission. DC: DC, on the other hand, is a type of electrical current that flows in only one direction, from the source
