Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a current amplifier with an input current of 5 mA and an unloaded current gain of 10, calculate the output current.

💡 Hint: Look at how gain modifies the input current.

Challenge 2 Hard

A current amplifier has a loading resistance of 50 ohms at the output and an internal resistance of 100 ohms. Given an unloaded output current of 60 mA, compute the actual output current.

💡 Hint: Consider how the load divides the current.
