Challenge Problems
Push your limits with advanced challenges
You have a common collector amplifier where input voltage is applied, and the collector is loaded with a resistance R_c. Calculate v_out when the load draws a current of 10mA, given that input voltage is 1V and R_c = 100Ω. What is the expected gain?
💡 Hint: Don't forget to account for voltage drops across load resistors.
Analyze how changes in R_c to 500Ω affect the voltage gain in the same common collector amplifier. What do you expect in terms of output voltage change?
💡 Hint: Focus on how each resistance influences overall circuit operation.
