When electrons flow in one direction only along a conductor, the current is called_______?

• A. Alternating Current
• B. Direct Current
• C. Radiant Current
• D. Static Current

Answer: (B)

When electrons flow in one direction only along a conductor, the current is referred to as Direct Current. This type of current maintains a constant polarity and direction, which results in a steady flow of electric charge. Common sources of direct current include batteries and solar cells. In contrast, alternating current periodically reverses direction, which is not the case with direct current. While radiant current is related to the transfer of energy through electromagnetic waves, and static current relates to accumulated charges that may discharge under certain conditions, these do not describe a continuous, unidirectional flow of electrons like direct current does. Understanding the characteristics of direct current is essential in many applications in dental radiography and other medical fields, where stable and consistent electrical flow is required for equipment operation.
