Challenge Problems
Push your limits with advanced challenges
Design a circuit using an n-p-n transistor model where β=100, and I_B is set to 0.1 mA. Evaluate I_C and determine the collector-emitter voltage drop if it is 10V.
💡 Hint: Start with applying the formula for current gain, and evaluate the drop accordingly.
If a p-n-p transistor has a β of 30 and an emitter current (I_E) of 15 mA, calculate the base current (I_B) and collector current (I_C).
💡 Hint: Use relationships among I_C, I_B, and I_E to solve.
