Diódának

Diódának is a term that refers to a diode, an electronic component that conducts current primarily in one direction. It is a semiconductor device with two terminals, an anode and a cathode. The flow of electricity from the anode to the cathode is permitted when the diode is forward-biased, meaning a positive voltage is applied to the anode and a negative voltage to the cathode. Conversely, when reverse-biased, with a negative voltage at the anode and a positive voltage at the cathode, very little current flows through the diode. This rectifying property is the fundamental characteristic of diodes and makes them essential in a wide range of electronic circuits.

Diodes are commonly used to convert alternating current (AC) to direct current (DC), a process known as rectification. They are also employed in voltage regulation, signal demodulation, and as protective elements against voltage spikes. Different types of diodes exist, each with specific properties and applications. For example, light-emitting diodes (LEDs) produce light when current passes through them, while Zener diodes are designed to maintain a stable voltage across them. The construction of a diode typically involves a junction between a p-type semiconductor material and an n-type semiconductor material, forming a p-n junction.
