Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given that the input current is 10 mA and the output current you measure is 9.8 mA, calculate the current gain and discuss its significance.

💡 Hint: Ensure you divide appropriate values from the given measurements.

Challenge 2 Hard

If a common base configuration has a transconductance (g_m) of 2 mA/V and an emitter voltage of 3V, what would be the output current?

💡 Hint: Use the provided transconductance value and the voltage correctly in the formula.
