Challenge Problems
Push your limits with challenges.
Question 1
Given an n-p-n BJT with a forward-bias voltage of 0.7V across the base-emitter junction and a reverse-bias of 5V across the base-collector junction, calculate the expected collector current assuming Ξ² = 100 and base current of 20 Β΅A.
π‘ Hint: Consider how the collector current amplifies the base current.
Question 2
Why would decreasing the base width of a BJT affect the collector current? Provide a detailed explanation.
π‘ Hint: Think about how the base influences the behavior of electrons crossing into the collector.
