Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A BJT has a beta (B2) of 150. If the base current is 20μA, calculate the collector current.

💡 Hint: Apply the current gain formula.

Challenge 2 Hard

Given a PNP transistor in a circuit, if the V_BE is 0.7V leading to a collector current of 2mA, explain how changing the temperature might affect the characteristic graph.

💡 Hint: Links between temperature effects and current flow should guide your explanation.
