Challenge Problems
Push your limits with advanced challenges
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 β = 100 and base current of 20 µA.
💡 Hint: Consider how the collector current amplifies the base current.
Why would decreasing the base width of a BJT affect the collector current? Provide a detailed explanation.
💡 Hint: Think about how the base influences the behavior of electrons crossing into the collector.
