Question 1
What occurs at the base-emitter junction during normal operation?
- It's reverse biased
- It's forward biased
- No bias is applied
💡 Hint: Consider the current entry point into the BJT.
Question 2
True or False: The reverse current in a BJT is mainly due to the movement of majority carriers.
- True
- False
💡 Hint: Focus on the definitions of minority and majority carriers.
