Challenge Problems
Push your limits with challenges.
Question 1
If a common-emitter amplifier has a supply voltage of 15V, R_B of 50kΩ, and V_BE(on) of 0.7V, calculate the base current. Then find the collector current if β is 100.
💡 Hint: Remember to apply Ohm's law for the base current.
Question 2
Given a common-collector amplifier configuration with R_E = 2.2kΩ and V_CC = 12V, calculate the output resistance if the transistor provides β = 100.
💡 Hint: This formula applies to output resistance seen from the emitter.
