Question

why the stability of the collector feedback bias

circuit is better than a fixed bias circuit​

Answer 1

Explanation:

Collector Feedback Biasing a Transistor

Collector Feedback Biasing a TransistorThe collector to base feedback configuration ensures that the transistor is always biased in the active region regardless of the value of Beta (β). The DC base bias voltage is derived from the collector voltage VC, thus providing good stability.
