Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a circuit using a p-n-p transistor. Describe the component values you would use to ensure the transistor remains in its active region.

💡 Hint: Sketch the circuit and label each part, focusing on biasing.

Challenge 2 Hard

If a circuit shows an n-p-n transistor with a base resistor of 1kΩ and a collector resistor of 4.7kΩ, calculate the collector current under given conditions where the base current is 8mA.

💡 Hint: Estimate β and consider how it relates to the provided currents.
