Exicom Electrical Engineer Interview Questions, Process, and Tips

Q1. Explain functions of zener diode and voltage regulation
Ans. 
Zener diode functions as a voltage regulator by maintaining a constant output voltage despite variations in input voltage.
• Zener diode conducts in reverse bias at a specific voltage called the breakdown voltage

• It maintains a constant voltage across its terminals, useful for voltage regulation in circuits

• Used in voltage stabilizers, voltage references, and surge protectors

• Helps protect sensitive components from voltage s
