Why bias a transistor ?

   What is the importance of biasing ? 👇👇

transistor 

The  purpose  of  dc biasing  of a  transistor is to obtain  a certain dc  collector current at a certain dc collector voltage. these values of current  and  voltage are expressed by the term operating  point (quiescent point) .  To obtain  the  operating  point, we  make use of some  circuits;  and these circuits are  called "biasing circuits" .Of course  , while  fixing the  operating  point,  it has to be seen  that  it  provides  proper dc  conditions  so that  the  specific  function of the  circuit is  achieved.  the suitability of an  operating point for the  specific  application  of  the circuit  should  be  seen on the transistor  characteristics.
