ASSIGNMENT 1

1-63. The suppressor grid of a pentode isoperated at what potential relative to(a) the cathode and (b) the plate?Figure 1C.—Basic tetrode circuit.1-60. What is the function of C sg in figure 1Cabove?1. It serves as a feedback capacitor2. It bypasses ac signals from thescreen grid to ground3. It keeps dc voltages from beingapplied to the screen grid fromground4. It couples ac signals from thecathode to the screen grid1-61. Which of the following undesirablecharacteristics is/are associated withtetrode operation?1. The plate is isolated from theelectron stream2. The plate emits secondary emissionelectrons3. The output is noisy4. Both 2 and 3 above1-62. Generally, tetrodes have a lowertransconductance than triodes. This iscaused by what feature of a tetrode?1. The plate is isolated from theelectron stream2. The screen grid draws current fromthe electron steam3. Secondary emission limits theamount of current the plate can drawfrom the electron stream4. The screen grid is operated at anegative potential relative to theplate and electrons are repelled fromthe plate1. (a) Positive(b) The same potential2. (a) Negative(b) The same potential3. (a) The same potentia(b) Negative4. (a) The same potential(b) Positive1-64. Voltage is supplied to the suppressorgrid in a pentode from what source?1. Through a resistor from the platesource voltage2. Through a resistor from ground3. By a separate voltage source4. By a physical connection from thecathode1-65. The suppressor grid is able to control theeffects of secondary emission by usingwhich of the following electronicactions?1. By attracting electrons emitted bythe plate through electromagneticattraction2. By repelling electrons emitted bythe plate through electromagneticrepulsion3. By attracting electrons emitted fromthe plate through electrostaticattraction4. By repelling electrons emitted fromthe plate through electrostaticrepulsion8
