Continental Device India Interview Questions, Process, and Tips

Q1. What are diodes and semiconductor
Ans. 
Diodes are electronic components that allow current to flow in one direction only, while semiconductors are materials with conductivity between that of insulators and conductors.
• Diodes are used in rectifiers to convert AC to DC power

• Semiconductors are used in electronic devices like transistors and integrated circuits

• Diodes have a forward voltage drop, typically around 0.7V for silicon diodes

• Semiconductors have a band
