Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
