Diode and Rectifier Differences in Physics Import Concepts Must to Know

Question. Difference Between Diode and Rectifier.

Answer:

Diode:

  • Let us now know what is diode. Diodes are used to protect circuits by limiting the voltage and to also transform AC into DC.
  • Semiconductors like silicon and germanium are used to make the most of the diodes.
  • Even though they transmit current in a single direction, the way with which they transmit differs.

Rectifier:

  • A rectifier is an electronic device that converts an alternating current into a direct current by using one or more P-N junction diodes. A diode behaves as a one-way valve that allows current to flow in a single direction. This process is known as rectification.
  • A rectifier can take the shape of several physical forms such as solid-state diodes, vacuum tube diodes, mercury-arc valves, silicon-controlled rectifiers, and various other silicon-based semiconductors switches.

Different Types of Rectifiers

Rectifiers are mainly classified into two types as:

  1. Uncontrolled Rectifier
  2. Controlled Rectifier

Differentiating PropertyDiodeRectifier
WorkingA diode only allows the flow of current through it only when it is forward biased.Rectifiers are used to convert the supply of AC to DC.
Current capacityThe current carrying capacity of the diode is low.The position of current capacity in rectifiers is high.
TypeThere are many types of diodes such as a photodiode, Zener diode, and more.There are two types of rectifiers: single-phase and three-phase rectifiers.
ApplicationA diode is used in switches and clippers.Rectifiers are used in computer systems.
MaterialA diode is made of germanium and silicon.Rectifiers are made of metals like copper, silver, and iron.
