Rectification MDCAT Quiz is the process of converting alternating current (AC) to direct current (DC), a crucial operation in many electronic devices. The most common method of rectification is the use of diodes, which allow current to flow in only one direction, hence “rectifying” the AC signal. There are two major types of rectification: half-wave rectification, where only one half of the AC waveform is used, and full-wave rectification, where both halves of the AC waveform are utilized. Rectification is the foundation of power supplies, battery charging circuits, and signal processing systems. For MDCAT students, understanding rectification is key for solving problems related to the behavior of diodes, circuits, and the conversion of AC to DC in electronics.
