THE LOAD LINE
A conventient graphical construction may be employed to find the output components for any operating condition. This construction is show in Figure 8, which consists of the plate characteristics of the tube in question and a superimposed load line. The load line is a graph of the equation which is evident from the circuit of Fig. 7. Any point on the line represents a possible combination of platte current, and no other combinations are possible.
The load line is most readily drawn by use of two points.
If the grid-bias voltage is E the zero-signal or quiescent condition is represented by the point P, which is the intersection of the load line with the plate characteristic corresponding to eb. This point will be referred to as the operating point, and when the signal voltage ec is applied, the instantaneous relation between plate current and plate potential will be represented by a point oscillating about P along the load line. If the range of this oscillation is between A and B, the plate potential will fluctuate between eb and Ec and the peak value of A.C. plate voltage will take place.
Steady and alternating components of plate current can be read from the diagram in the same manner.
The operation of a tube with resistance load can also be represented by a line drawn on the plot of mutual characteristics, but in this case the line depends not only on the

to occur at temperatures, in the same manner, in some manner, no other combinations are possible.
Answer the questions
1. What may a convenient graphical construction be employed for? 2. In what case is the zero-signal or quiescent condition represented by the point P? 3. By what can the operation of a tube with resistance load be represented?
