Challenge Problems
Push your limits with challenges.
Question 1
A BJT is used in a circuit where it needs to switch loads on and off quickly. Discuss which mode of operation is most suitable and explain why.
💡 Hint: Consider the behavior of a switch.
Question 2
In a specific application, losses during switching are significant if the BJT is not managed correctly. How can addressing the cut-off and saturation modes influence efficiency?
💡 Hint: Focus on the on/off cycle of the transistor.
