Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You have a current amplifier with a current gain of 10 and connect a load resistance of 100Ω. If the input current is 1mA, calculate the output current.

💡 Hint: Consider how load resistance divides the total current out.

Challenge 2 Hard

Design an amplifier stage where the output is affected by loading effects. Propose how you would adjust the input parameters to optimize performance.

💡 Hint: Reflect on the effects of input and output resistances in practical applications.
