Challenge Problems
Push your limits with advanced challenges
Calculate the impact on collector current if the base-emitter voltage is increased from 0.7V to 0.8V while keeping the characteristics of the BJT constant.
💡 Hint: Use the exponential relationship of current with voltage in your calculations.
In a lab experiment, the recombination current was measured to be 5 μA while the injection current was 20 μA. Determine the net effect these currents will have on the base current.
💡 Hint: Focus on the concept of how injection and recombination balance out in the calculations.
