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.
How do you choose q point on load line?
the fixed amount of current and voltages are developed across the transistor is called biasing. thus the fixed voltages and current developed are called Q-point
What are the endpoints of the DC load line?
cutoff and saturation
What are cut-off and saturation points in a dc load line?
The cut-off point is the exact point where the load line crosses with the vector axis. The saturation point is the point where the load line intersects with the collector current axis.
What is the shape of slope used for DC load line of a transistor?
It depends on the total load of the transistor as to what the shape of the slope is for the DC load line. A transistor gains voltage as base current is allowed to flow.
What is the significance of dc load line in a transistor?
A load line is used in graphic analysis of circuits, having both linear and non-linear parts, representing the constraint the other parts of the circuit put on the non-linear transistor. It represents the response of the linear circuit connected to the transistor. The DC load line describes the DC operation of a transistor graphically.
What is a load line of transistor?

Quiescent operating point of a transistor amplifier lies in?
It lies in middle of the DC load line of that Amplifier.
What are Ac load lines in an amplifier and how they are drawn?
The dc load resistance is Rc but the AC Load resistance is (RcRl). If a load line is drawn the slope of which is -1(Rc Rl) . Then it is called an AC load line and it is to be used when the transistor is operating as an amplifier.
Difference between dc load line and ac load line?
well the difference mainly exists in the method of finding them , these are :-1. in finding DC load line :-open all AC sourcesopen all the capacitors2. for AC load line:-open all the Dc sourcesshort all the capacitors.
Ac and dc load line of BJT-explain?
when the dc supply given, dc load line lies in the Ic and Vcc. when the AC supply given, AC load line lies in the Ic and Vcc.
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.
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 dc load line?
well, this is very simple to understand ,the DC load line of a circuit is nothing but the Kirchoff's voltage law on the out put circuit of the transistor-amplifier. As the KVL is linear equation involving voltage drops the equation of load line is a straight linelet us assume that the transistor is in CE configuration.VCC-VCE-ICRC=0vICRC=VCC-VCE of the form by=aX+c which is in the form of a straight line with positive intercepts on X(VCC) and Y(VCC / RC) axis and a negative slopewhere,x= VCE/RCy= ICm(slope)= -VCC/RC

Aim of load line analysis of a transistor amplifier?
