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 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 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 are the endpoints of the DC load line?
cutoff and saturation
What is DC load line of a transistor?
A: A transistor has voltage gain as base current is allow to flow. If the load is constant then a DC mirror azimuth path can be plotted as a function of base current and collector current and that is the load line

Quiescent operating point of a transistor amplifier lies in?
It lies in middle of the DC load line of that Amplifier.
How do you select the operating point for the amplifier?
selection of operating point is very important in the electronics circuit designing or construction of amplifiers 1. operating point is generally selected as the point of intersection of both DC and AC load lines. 2. they may also be chosen as the mid-point of DC load line if maximum symmetrical swing of the signal is desired
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.
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 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.
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.
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 happens when load is removed from an operating series DC motor?
The speed will increase possibly to the point that it throws out the coils from the armature & self destructs.
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 are the endpoints of the DC load line?
cutoff and saturation
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.
