What is typically the primary function of a rectifier?

The primary function of a rectifier is to convert alternating current (AC) to direct current (DC). Rectifiers utilize components such as diodes which only allow current to flow in one direction, effectively blocking the reverse flow that characterizes AC. This conversion is fundamental in many electronic devices that require DC power for operation, such as batteries, power supplies, and various electronics circuits.

The rectification process ensures that the output is a steady DC voltage, which is crucial for providing a stable power supply. The ability to control the flow of electricity in this manner makes rectifiers indispensable in electrical engineering and electronics, allowing for the safe and efficient operation of devices that rely on consistent current flow.
