In the lower voltage range, around 115 V, this switch is turned on changing the power grid voltage rectifier into a voltage doubler in delon circuit design.

Plotting plate current as a function of applied grid voltage, it was seen that there was a range of grid voltages for which the transfer characteristics were approximately linear.

14.
The shunt capacitors are usually connected directly to the grid voltage but in some cases may be connected to a lower voltage via a tertiary winding on the converter transformer.
15.
The variation in anode voltage can be much larger than the variation in grid voltage which caused it, and thus the tube can amplify, functioning as an amplifier.
16.
Since below cutoff the plate current ceases to respond to the grid voltage, the voltage on the grid must remain above the cutoff voltage for faithful ( linear ) amplification.
17.
Since the grid voltage changes from-1.5 V to-0.5 V, and the anode resistor voltage drops from 12 to 33 V, an amplification of the signal resulted.
18.
Because of negative feedback ( the cathode-ground voltage cancels the grid-ground voltage ) the voltage gain is close to unity and the output voltage " follows " the grid voltage.
19.
The anode current is set by the value of the grid voltage relative to the cathode and this voltage is now dependent upon the value of the resistance selected for the cathode branch of the circuit.
20.
Using analog signals, 230 V in Europe make You hear the power grids frequency in double that loud than use at 115 V due installed Y-capacitors deliver half of the grid voltage to the equipment.
