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
Shunt elements are components in electrical circuits that are connected in parallel to a load or a circuit branch. They are used to divert a portion of current away from the main circuit, often for purposes such as voltage regulation, power factor correction, or protection. Common examples include capacitors and resistors used in shunt configurations. By managing the flow of current, shunt elements help improve circuit performance and stability.
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.
The power factor of a purely resistive circuit is 1.0.
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.
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.
of course stability of self bias circuit is much greater than fixed bias circuit

The different types of power factor are: # Leading ( Due to Capacitive Circuit) # Lagging (Due to Inductive Circuit) # Unity (Due to Resistive Circuit)

Improving power factor does nothing to improve a circuit. It merely affects the amount of current drawn by the load.
