Cathode and Anode of a Diode
In the context of a semiconductor diode, such as a typical silicon or germanium diode used in electronic circuits, the terms “cathode” and “anode” refer to the two terminals of the diode. Here’s how these terms are applied to a diode:
Cathode of a Diode
- Cathode in the diode is negatively charged.
- Electrons flow into the cathode during forward biasing (when the diode is conducting).
- In schematic symbols, the cathode is usually indicated by a line or arrow pointing away from the diode symbol.
Anode of a Diode
- Anode in the diode is positively charged.
- Electrons flow out of the anode during forward biasing.
- In schematic symbols, the anode is usually indicated by a line or arrow pointing toward the diode symbol.
Cathode and Anode
Cathode and Anode are commonly used terms in the context of electrochemistry, specifically in electrochemical cells like batteries and electrolytic cells. An anode is a negative or reducing electrode that releases electrons and oxidizes during an electrochemical reaction whereas a Cathode is a positive or oxidizing electrode.
In this article, we will learn about, Cathode, Anode, their differences, and others in detail.
