Voltas Graduate Trainee Interview Questions and Answers

Q1. Diode IV Characteristics
Ans. 
Diode IV characteristics describe the relationship between current and voltage in a diode.
• Diode IV characteristics show that current increases exponentially with voltage in the forward bias region.

• In the reverse bias region, diode IV characteristics show a very small leakage current until the breakdown voltage is reached.

• The knee voltage is the point where the diode starts conducting significantly in the forward bias r...read more
