What is the necessity of Q point in BJT study?
selection of q-point is necessary in amplifiers,because if the q-point is not in the middle of load line the output may be clipped i.e not in the power supply range.
What is the use of load line?
It helps us to select the Q - point of the BJT, MOSFET etc.
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 an operating point of dc load line?
operating point of dc load line refers to point where there is no signal either no amplification use to take place as base current is zero(in case of common emitter configuration) and it is represented by Q.......
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.
Why do you choose the Q point at the centre of the load line?
When operating point is chosen at the center of the load line, faithful reproduction of the amplified signal is obtained by allowing large voltage and current. So we choose q point at the center of the loadline.

How do you draw DC load line and determine the Q point?
we should be take two point from the the graph between collector current and emitter-collector voltage.. along the horizontal line collector current is zero and emitter-collector voltage become Vcc,and along the vertical line emitter-collector voltage is zero and collector current become Vcc/RL then by this line that drow between this two point is called load line that in this line the transistor allowed to operate....

What is the point slope equation if the slope is 2?
If (p, q) is any point on the line, then the point slope equation is: (y - q)/(x - p) = 2 or (y - q) = 2*(x - p)
What is the point-slope formula and how is it used?
Given a straight line with slope m and a point (p,q) on the line, the point-slope formula of the line is (y - q) = m(x - p) It is used to represent a straight line in the Cartesian plane. This allows techniques of algebra to be used in solving problems in geometry.
What is q line distillation?
It sounds like you are asking about calculating theoretical stages for distillation of a binary mixture using the McCabe-Thiele method, which includes calculation of the q line from the composition of the feed. The parameter q is the mole fraction of liquid in the feed and the slope of the q-line is q / (q - 1). The q line passes through the point defining the composition of the feed on the x=y line drawn on the diagram. For more details on the McCabe-Thiele method, see the attached link.
What precautions you must take in order to ensure that your amplifier operates in the linear region?
A: When the bias is set up that will not stay there if the load chabges. It really depends on the load for the Q point
Q and -q are two charges d distances apartFind locus of a point at which electric fields are parallel to the line joining the charges?
Seems to me it has to be the line that passes through the mid-point of the line joining the charges, and perpendicular to it. It would be a line with slope = -1 / (slope of line joining the charges) and passing through the point that's (d/2) distant from both charges.
