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 Effect of quiescent point close to cutoff?
The output voltage swing will not reach its maximum. This would then give clipping of one side of the signal which means the signal output is not a amplified representation of the original signal.
What is stability of transistor?
Transistors need thermal stabilization because the operating point of a transistor junction, similar to a diode, is affected by temperature. In fact, this can cause thermal runaway, and device destruction, if the circuit design does not compensate for this. Answer mostly correct but the operating point of a transistor must remain fixed as temperature varies whether going low or higher. that is mainly the concern about. not runaway that is caused by bad design.
What is difference between AC and DC load line?
A dc load line is formed by joining the 2 points wherin the slope is equal to the inverse of the load resistance.. whereas the ac load lin has a different slope... and it intersects the dc load line at the quiescent 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.
What is the meaning of quiescent point?
it is a point on a load line where no signal appears
Quiescent operating point of a transistor amplifier lies in?
It lies in middle of the DC load line of that Amplifier.
What are the factors affecting the stability of a Q-point?
(1) current amplification factor due to change in temperature. (2) collector current because of variation in leakage current.
What are the factors affecting stability of q point?

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

Heat will flow from a hot object to a cold object until the objects reach A. stability. B. equilibrium. C. collapse. D. boiling point?
stability
What does a liquid substance have?
A liquid has a density, refractive index, freezing point, boiling point, thermal stability, compressibility, viscosity etc.
What does the yellow exclamation point light mean on a Honda Accord?
The yellow exclamation point light on a Honda Accord is designed for the Vehicle Stability Assist system. It comes on when the vehicle is trying to maintain stability or when a tire is low.
Who is responsible for damages done during eviction?
You are. YOu are responsible for a unit until you have completely moved out and turned in the keys. At that point, you are no longer responsible for any damages as you are officially not living there and therefore, no longer responsible. But up until that point, you are responsible as you are still officially a tenant, which would include the eviction process.
