Response to the following:
An npn transistor of a type whose β is specified to range from 50 to 300 is connected in a circuit with emitter grounded, collector at +10 V, and a current of 10 μA injected into the base. Calculate the range of collector and emitter currents that can result. What is the maximum power dissipated in the transistor?
(Note: Perhaps you can see why this is a bad way to establish the operating current in the collector of a BJT.)
