Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A BJT with beta = 50 and a base current of 5 mA is in active mode. Calculate the Emitter and Collector currents.

💡 Hint: Use the current relations we've discussed.

Challenge 2 Hard

You have a circuit where the BJT operates in saturation mode. Describe your observations about the Collector current and the other currents.

💡 Hint: Consider what happens to the current flow when both junctions are forward biased.
