HANDBOOK OF PROJECTION FOR Using the rubber band as an example, describe the action of an electrical condenser 1021 In what manner may the capacity of a condenser be altered? 1022 Is electricity really "condensed" in a condenser? 1023 Vacuum Tube as an Amplifier What does the "amplifying tube" really do? 1025 What happens when a filament is sealed in a vacuum and an electric current sent through it? 1025 What is an "electron" ? 1025 How do electrons thrown off by a hot filament travel ? 1025 In what manner are electrons made to "amplify" current? 1025 Is there any known substitute for the amplifying tube? 1026 Describe the amplifying tube 1026 Is the plate, the grid and the filament positively or negatively charged ? ' 1028 What is the relative speed of electric action as compared with the speed of sound ? 1028 Does an ordinary incandescent globe filament throw off electrons and, if so, why cannot it be used for amplifying ? 1028 Describe the action of the filament, the plate and the grid in detail 1029 Upon what will the flow of electrons from filament to plate be directly dependent ? 1030 What are amplifying tubes called in Europe? 1031 Are amplifying tubes connected in series or parallel? 1031 How is it that while a steady negative voltage is applied to the grid, the grid voltage nevertheless is vibrating or fluctuating ? 1031 In what manner would you clean the contact stud at the base of an amplifying tube? 1046 In certain types of installations the amplifying tubes are held in suspension by springs. What precaution is necessary ? 1047 The Vacuum Tube as a Rectifier Why should an amplifying tube never be used for rectifying current ? 1033 What is the frequency of most commercial electric current? 1033 Why is a full wave action called a "cycle" ? 1034 Why will not electrons flow from plate to filament? 1034 If a tube with a grid be used for rectifying current, what should be done with or about the grid?.... 1035 xviii
