A: A circuit to be useful to do work must be stable with the environment and also with reliable circuit performance. A circuit that is allow break into oscillation or other criteria is not stable therefore not much useful.
The power factor of a purely resistive circuit is 1.0.
A resistor doesn't have a power factor. However, if a circuit is pure resistance in nature the power factor will be one when a voltage is applied and a current flows in the circuit. The power factor is a measure of the relative phases of the current and voltage in a circuit.
Minimize circuit resistance.
To improve the power factor
Transistors need thermal stabilization because the operating point of a transistor junction, similar to a diode, is affected by temperature. In fact, this can cause thermal runaway, and device destruction, if the circuit design does not compensate for this. Answer mostly correct but the operating point of a transistor must remain fixed as temperature varies whether going low or higher. that is mainly the concern about. not runaway that is caused by bad design.
for a collector to base biased circuit find the stability factor s?what is the effect on s for change in current amplification factor?
In a RLC series circuit the Q factor magnify the voltage to the circuit.
of course stability of self bias circuit is much greater than fixed bias circuit
it has high stability large q factor and the frequency that doesn't drift with aging. It is used as a clock source most of the times.
