WebIt is called the operating point because the variations of Ic and Vce take place at this point when an input signal is applied. This point is also called as Q point or quiescent (Silent) point because it is a point of output characteristics when a transistor is silent i.e. in absence of the signal. For operating point, we have to find load line. Web1.Fixed bias (base bias): The single power source (for example, a battery) is used for both collector and base of a transistor, although separate batteries can also be used. In the given circuit, Vcc = IbRb + Vbe. Therefore, IB = (Vcc − Vbe)/Rb. For a given transistor, Vbe does not vary significantly during use.
