What process involves converting alternating current (AC) to direct current (DC)?

The process of converting alternating current (AC) to direct current (DC) is known as rectification. This conversion is essential in various applications where DC is required because many electronic devices and circuits operate on DC. Rectification typically involves the use of diodes or rectifiers, which allow current to flow in only one direction, effectively converting the back-and-forth flow of AC into a one-directional flow of DC.

Understanding rectification is crucial, especially in radiology, where certain imaging systems and devices utilize DC power for stable operation. Proper rectification ensures that these devices function efficiently and effectively, avoiding potential errors or malfunctions that could arise from using AC directly.

Other processes mentioned, such as transmission, pertains to the process of transporting electrical energy over distances and does not involve conversion of current types. Transformation refers to changing voltage levels in AC systems, often using transformers, while conduction deals with the movement of electric charge through a conductor, neither of which directly involves converting AC to DC.
