Figure 3-4 below shows a triode circuit and a graph of the plate
characteristics of the triode. The operating point of the triode is
indicated on the characteristics by point Q. At point Q, the plate
current is 7.0 mA and plate voltage is 210 volts.
Exercises 3 through 7 are based on the above situation.
