Challenge Problems
Push your limits with challenges.
Question 1
A diode is implemented in a circuit. If the temperature of the circuit increases significantly, how would you predict the behavior of the diode under both forward and reverse biases?
💡 Hint: Reflect on the relationships between charge carriers, temperature, and the components of the diode.
Question 2
In a lab setting, you observe that a certain PN junction diode has a very low reverse saturation current. What does this imply about the properties of the diode, and how could it influence its applications?
💡 Hint: Consider the implications of efficiency in semiconductor devices.
