Challenge Problems
Push your limits with challenges.
Question 1
If a current amplifier has an unloaded gain of 10 and the input current is 2mA, calculate the output current when a load of 1kΩ is connected and the output resistance is 500Ω.
💡 Hint: Use the unloading current formula while accounting for output resistance.
Question 2
Design a lab experiment to visualize the effect of varying load resistance on output current in a current amplifier. Include method and expected outcomes.
💡 Hint: Consider using a multimeter for reading output current.
