    Quiescent point is basically an operating or bias point. This point on the load line specifies the DC current in transistor & the voltage across it especially in the absence of ac signal. Thus, Q-point represents the DC bias condition.
    Generally, the position of Q-point on the load line depends on the functionality of transistor. If the purpose of a transistor is an amplification, then the assigned position of Q-point is intended at the center of the load line.
    This position is assigned with an intimation of preventing the distortion level from getting introduced in an amplified output of an ac waveform.
