Abhishek RawalQ point is also known as Quiescent point or bias point which means "inactive".It is point on dc load line that represents Idc (dc current) through transistor & Vdc(Voltage) across it when no ac is applied.
In any transistor configuration (CE,CC or CB) whenever Kirchhoff's law is applied to given configuration of circuit & taking the load current into consideration the equation which will be obtained will be of pattern of straight line i.e. y=mx+c,this straight line represents load line.There are two types of load lines :ac load line & dc load line.According to slope obtained it is characterized.-1/Rc(dc load line - no ac signal i/p) & -1/Rc||RL(ac loadline).
The position of Q point on loadline depends on its application.For eg:Q point will be in active region in Amplifiers.The shape of o/p in amplifiers depends upon q point's position.
Well I dunno how to explain this huge theory in forum though i tried my best. 😀
