Why emitter bias circuit is called self bias?

The emitter bias circuit is called self-bias because the bias voltage across the emitter-resistor is based on the transistor's own characteristics. The bias voltage adjusts itself based on the varying collector current to stabilize the operating point of the transistor. It is a self-adjusting mechanism that helps maintain a stable bias point for the transistor.


What are the factors that affect the bias stability of a transistor?

temperature


Why a transistor can be operated in active region?

a transistor can only work in active region cox in active region collector base junction is in reverse bias and emitter base junction is in forward bias.
