Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Analyze a circuit containing a p-n-p transistor with an emitter voltage of +10V, a base voltage of +7V, and a collector voltage of +5V. What are the biases, and is the transistor in the active region?

💡 Hint: Check if voltage conditions meet active region requirements.

Challenge 2 Hard

Design an n-p-n transistor circuit using a supply voltage of 12V. If you have a resistor of 2kΩ in the base, determine the emitter current assuming beta = 100.

💡 Hint: Begin with Ohm's Law to find base current first.
