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 loading effect?
An instrument to be able to really tell the value is mandatory that the instrument does not load the circuit making it a false reading or inaccurate loading effect which means when we give high load that may be cause to some fake or inaccurate of output, this may be known as loading effect....
Do higher watt inverters drain batteries more than lower watt?
The inverter draws little current on its own. It is the load that is connected to the inverter. If there were no load on the inverter you could use an ampmeter to determine the no load current. One thing to consider is that a higher wattage inverter would have larger gauge wire which is of lower resistance. This could make the no load current lower for the higher wattage inverter. Bottom line is you would have to measure or have a specification on the no load current.
How a transformer can be used as impedance matching?
If the line impedance is Z0 and the load is ZL then connect the load using a transformer with N turns ration. N=sqrt(Z0/ZL)
What is the load side of a transformer?
The load side of a transformer feeds the device, such as a light or motor. It is the output of the transformer. The input, or line side, provides the voltage that is to be transformed, either up or down, to supply the load side.AnswerA transformer's primary winding is connected to the supply voltage, and the secondary winding is connected to the load.
What is the difference between Load Current Line Current and Phase Current?
A load current is a current drawn by an electrical load. In other words, it is the current flowing from the source to the load.For a single-phase system, a line current is a current flowing through the line, or 'hot', conductor, while the current through the neutral conductor is called the neutral current.For a three-phase system, the three 'hot' conductors between the load and the source are called 'lines' and, so, the currents passing through them are called 'line currents'. For a three-phase system, loads are either connected between line conductors (delta-connected system) or between each line and the neutral (star- or wye-connected system), and represent the phases -so the currents passing through the loads are called 'phase currents'.For a balanced three-phase system, the line current is 1.732 times the value of a phase current, where the phases (loads) are connected in delta. For phases (loads) connected in star (or 'wye') the line current is numerically-equal to the phase currents.
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 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 the meaning of quiescent point?
it is a point on a load line where no signal appears
What is the definition of Sag current in transmission line?
sag means the deepest point of the conductorAnswerSag is defined as follows: 'Sag, under any system of conductor loading, is the distance measured in the direction of the resultant load, between the conductor and the midpoint of a straight line joining adjacent supports'.So, draw an imaginary line beween two adjacent supports (towers or poles) and, from the midway point, draw a vertical line to where it intersects the conductor, and that vertical line represents the sag.
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.
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.
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 loadings?
A continuous load is a constant load. A noncontinuous load is one that varies over time.
Aim of load line analysis of a transistor amplifier?
to achieve quiecent operating point
What is the use of load line?
It helps us to select the Q - point of the BJT, MOSFET etc.
What is a load line of transistor?
what is load line of transistor what is 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.
