What is the role of a diode in a semiconductor circuit?

Step 1: Understand what a diode is. A diode is a small electronic component that allows electricity to flow in one direction.
Step 2: Learn about current flow. In a circuit, current can flow in two directions, but a diode only lets it flow one way.
Step 3: Know the main function of a diode. The main role of a diode is to convert alternating current (AC) to direct current (DC), which is called rectification.
Step 4: Recognize where diodes are used. Diodes are commonly used in power supplies, radio signals, and other electronic devices to control the direction of current.
