Challenge Problems
Push your limits with advanced challenges
A BJT operates with a base-emitter voltage of 0.7V while the base-collector is reverse biased. Calculate the expected base and collector currents given the forward currents are known.
💡 Hint: Use I_C = Beta * I_B, where Beta is the current gain.
If a BJT shows a collector current of 2 mA with a base current of 20 µA, determine the beta and provide its significance.
💡 Hint: Beta shows how much the base current is amplified to the collector current.
