Challenge Problems
Push your limits with challenges.
Question 1
A BJT has a base current of 50 µA and a current gain (β) of 200. Calculate the collector current and discuss its significance in a circuit application.
💡 Hint: Make sure to remember the collector current equation!
Question 2
If a BJT's reverse saturation current is 1 nA and the applied reverse voltage is 10 V, discuss the effect this has on the junction operation and explain why this condition is essential in the design.
💡 Hint: Consider how the reverse bias affects the depletion region size.
