When electrons flow in one direction and then reverse to flow in the opposite direction, the current is called______?

When electrons flow in one direction and then reverse to flow in the opposite direction, the current is called______?

• A. Direct Current
• B. Alternating Current
• C. Pulsating Current
• D. Constant Current

Answer: (B)

The phenomenon described in the question refers to how the electrons behave in an electrical circuit. When electrons flow in one direction and then reverse to flow in the opposite direction, this creates an alternating current. Alternating current (AC) is characterized by the periodic change in direction of the flow of electric charge. This type of current is commonly used in household power supplies and is efficient for long-distance transmission of electrical energy. In contrast, direct current (DC) is the flow of electric charge in a single direction, which means the electrons do not reverse their flow. Pulsating current represents a type of current that varies in amplitude rather than direction and can resemble AC, but it does not specifically describe the back-and-forth flow typical of AC. Constant current refers to a situation where the current remains steady over time, without fluctuations, and does not account for the changes in flow direction. Understanding the properties of alternating current is essential in various applications, including electrical engineering and any work that involves electrical devices, thus making it a fundamental concept in the study of radiation safety and the operation of dental equipment.
