With a 14-volt peak-to-peak signal, the maximum positive swing
of signal voltage will be 7 volts. Therefore, a fixed bias of minus
8 volts will maintain the grid at a negative value.

On the 200-volt plate voltage curve, a current of 3.4 mA is seen
to correspond to a grid voltage of -8 volts. When the plate voltage
is increased to 250 volts, the 250-volt curve shows a plate current
of 8.9 mA corresponding to a grid voltage of -8 volts.
Thus the
increase in plate current is:
8.9 - 3.4 = 5.5 mA.
