Direction of current flow in forward bias
How do Avalanche Diodes operate?
Through the avalanche effect in reverse bias
What is the primary function of a Photodiode?
Identifying small current flow due to light
What happens when the anode voltage is more positive than the cathode voltage in a diode?
The diode conducts with low voltage drop
Which materials are commonly used to make diodes?
Silicon and Germanium
What happens to a diode when the cathode voltage is more positive than the anode voltage?
It is reverse-biased
Learn about the functionality and symbol of diodes, electronic components that conduct electricity mainly in one direction. Discover how diodes are utilized to protect circuits, limit voltage, and convert AC to DC, with a focus on semiconductor materials like silicon and germanium.
