Question

Which of the following statements is most correct to explain role of biasing circuit in the implementation of a transistor circuit?

(a) It is used provide proper voltage to every component in the circuit

(b) It is used to ensure maximum power is obtained out of the circuit

(c) It is used to provide the quiescent collector current

(d) It is used to provide proper and stable functional environment to all quiescent point parameters

I got this question by my school principal while I was bunking the class.

The above asked question is from Characteristics of Amplifier topic in portion Transistor Biasing and Low Frequencies of Analog Circuits

Answer 1

Correct option is (d) It is used to provide proper and stable functional environment to all quiescent point parameters

For explanation: The basic function of biasing is to maintain amplifier in quiescent condition. The amplifier will properly work only if the quiescent condition is stable.
