Description

🔧 Product Description: HALF WAVE RECTIFIER

A Half Wave Rectifier is an essential electronic component used to convert alternating current (AC) into direct current (DC). It works by allowing only one half-cycle (positive or negative) of the AC signal to pass through, effectively blocking the other half. This process results in a pulsating DC output which is useful in many low-power applications and foundational learning in electronics.

This rectifier typically consists of a single diode and a load resistor. During the positive half-cycle of AC input, the diode becomes forward-biased and conducts, allowing current to flow through the load. This basic principle makes it a perfect component for understanding the fundamentals of rectification and semiconductor behavior.

In laboratories, half wave rectifiers are widely used in physics and electrical engineering experiments. Students use it to understand waveform transformation, diode characteristics, and the rectification process.
