Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A circuit uses an NPN transistor with a beta (β) of 50 and a base current (Ib) of 5 µA. Calculate the collector current (Ic) and the relations among emitter, base, and collector currents.

💡 Hint: Remember, Ic = β * Ib and relate the currents together.

Challenge 2 Hard

In a PNP transistor, if the emitter current (Ie) is measured at 3 mA and the base current (Ib) is 10 µA, determine the collector current (Ic) assuming β = 300.

💡 Hint: Understand the relationship between currents in the transistor.
