The voltage or Potential divider bias or the self bias circuit is the best biasing technique because,it has very low stability factor(change in collector current with respect to Ico or Vbe or current gain beta).
only in this technique the increase in temperature wont affect the collector current.

Why is it necessary to bias a transistor when it is to be used as an amplifier?
Biasing is necessary in a transistor circuit to keep the transistor working. Without proper biasing, the circuit will fail
What compensation technique is better than other techniques in transistor biasing?
That would depend on your application. If there was a singke best way, that would be the only method used.
What is the output impedance of common source amplifier circuit?
The output impedance of a common source amplifier circuit is typically high. This is because the common source amplifier uses a resistor to provide biasing, which results in a high output impedance. However, this can be mitigated by using a current source instead of a resistor for biasing.
How is transformer saturation avoided in class B push pull amplifier operation?
In class B amplifier no DC biasing required, thus lack of of DC current in inpunt and load, saturation of core avoided
Why you are giving dc supply for biasing the amplifier why not ac?
The purpose of biasing an amplifier is to shift its operating point, so that when you apply a signal in you will get a expected signal out. The operating point is generally in the middle of the linear region. You would not use AC for the bias, as that would cause the operating point to constantly shift, and you would then not be able to differentiate between the signal and the bias.
What are the different types of biasing technique for amplifier?
Base resistor method (or) Fixed bias methodBiasing with feedback resistor (or) Collector to base bias methodVoltage divider bias (or) Self bias
Why is it necessary to bias a transistor when it is to be used as an amplifier?
Biasing is necessary in a transistor circuit to keep the transistor working. Without proper biasing, the circuit will fail
What is DC coupled amplifier?
A: DC couple amplifiers refers to stages of amplifiers where is the biasing is direct without adding capacitors to remove the DC component from amplifier to amplifier
What are operating point int transistor biasing?
A: An operating in biasing is determined by the transistor capabilities as a linear amplifier. Basically it is a bias to insure linear operation with the loading of the output
What are the biasing roles of transistor?
A: Transistor to be effective as an linear amplifier it must be operated in its linear load range. The biasing scheme is to insure that the transistor is put in its linear/load range
What compensation technique is better than other techniques in transistor biasing?
That would depend on your application. If there was a singke best way, that would be the only method used.
Is paper capacitor use in transistor amplifier?
It can be, but may not be required. Capacitors are used for biasing purposes, to remove DC from inputs, and for filtering in amplifier circuits (just to name a few).
What is the output impedance of common source amplifier circuit?
The output impedance of a common source amplifier circuit is typically high. This is because the common source amplifier uses a resistor to provide biasing, which results in a high output impedance. However, this can be mitigated by using a current source instead of a resistor for biasing.
What is a function of baising?
what is a function of Biasing and explain it's working ? why the Common Emitter Configuration is use as Amplifier ? Explain in Detail ?

Which biasing is known to as universal biasing?
voltage divider biasing
