The operating point of a transistor is simply the point, or circuit condition, where it is biased.
With no signal present, the operating point sets the collector-emitter current, and the resulting voltages. Ideally, the operating point is chosen to be the midpoint of the linear region of operation, so as to minimize distortion and to maximize range.
Since transistors have varying gains (hFe), and since the gain is temperature dependent, the operating point is usually chosen to be a range that also maximizes stability and minimizes the variability of the individual transistor.

What is the purpose of dc biasing of transistor?
to establish Q- point or operating point...
What is q-point of transistor?
The operating point of a device, also known as bias point or quiescent point (or simply Q-point), is the DC voltage and/or current which, when applied to a device, causes it to operate in a certain desired fashion. The term is normally used in connection with devices such as transistors and diodes which are used in amplification or rectification.
Define the operating point of a transistor how it is stabilized and why it should be stabilized?
The operating point of a device, also known as bias point, quiescent point, or Q-point, is the point on the output characteristics that shows the DC collector-emitter voltage (Vce) and the collector current (Ic) with no input signal applied. The term is normally used in connection with devices such as transistors.
What is the relation between transistor operating region and bias conditions?
A: Depending on the load each linear operating region depends on the load and the correct bias insure it ANSWER: The relationship is strictly related to the bias Change the bias you change the operating region point of departure
Why you use capacitor before connecting transtitor?
Before connecting to the transistor we use a capacitor becausefor the transistor to amplify we should first apply DC biasing so that we can set an operating point to itso once the transistor is biased DC currents flow in the whole circuitryAll the AC signal source are shorts to the DC currents so we employ capacitor for two reasons1.As capacitor blocks DC and allows AC it is connected for not moving the DC operating point of the transistor and making it fixed since if any small DC part arises in the signal it leads to the change of operating point and our amplification procees gets affected2.To block the already present DC currents in the circuitry for not getting away and making it fixed
Why operating point of transistor is called as q point?
Q-point means motionless point. At operating point the transistor emitter current and collector current doesn't change. That is why operating called as a quiesent point (q-point)
How operating point of transistor shifting?
Usually, the operating point of a transistor shift because of temperature induced gain or bias changes.
Why transistor is to be biased?
to set its operating point
What is the operating point in transistor biasing?
The operating point of a transistor is the point on its conduction curve that the engineer has selected for its operation, based on the intended function of the circuit the transistor is used in. This will vary with this function:a class A amplifier will have its operating point in the center of the linear range of the conduction curve.a class B amplifier will have its operating point at the cut off point of the conduction curve.logic gates will usually have the operating point near the cut off point off the conduction curve.etc.

What is Q point of a transistor?
Q point which is quiscent (silent) point is the operating point of a transistor where the variations of collector current and collector-emitter voltage take place when signal is applied.
What are operating point int transistor biasing?
A: An operating in biasing is determined by the transistor capabilities as a linear amplifier. Basically it is a bias to insure linear operation with the loading of the output
What is the point of Q?
Q point is also called operating point.Q point is mainly adjusted in transistors to make it stable. i.e., to operate the transistor in safe mode. Depending up on the operating current and voltage Q point is adjusted. The Q point defines the operating condition of the transistor and the transistors which quiescent point is adjusted are denoted as Q1,Q2.........Qn
Aim of load line analysis of a transistor amplifier?

Quiescent operating point of a transistor amplifier lies in?
It lies in middle of the DC load line of that Amplifier.
