Challenge Problems
Push your limits with challenges.
Question 1
Design a current amplifier circuit that can achieve a gain of 50 with a load of 200 ohms. What components do you need, and how would you configure them?
💡 Hint: Start by calculating the necessary input current based on desired output current.
Question 2
Evaluate how the output current of a current amplifier would change if the load resistance is halved. Provide the equation used for your calculations.
💡 Hint: Relate the output current change to both gain and new load resistance.
