Рубрика: 

A. By the way, our English teacher said that we should be asked questions on
our specialty in English.
B. I think it would be very useful to practise some questions and answers be-
fore the exam.
A. That's an idea 'Let's do it now. Here is the article: "Physical Construction of
Cathodes". Can you ask me some questions?
B. Certainly, I can. What types of cathodes are employed in vacuum tubes?
A. Oh! It's very simple. Two types are employed: the filamentary and the indi-
rectly heated.
B. That's correct. Here is another question. At what potential are the different
parts of the
cathode if alternating current is used for heating?
A. They are not at constant potential, on account of the IR drop of the current.
B. I see that all my questions are too easy for you. And now answer my last
question: what are
the advantages the indirectly heated cathode?
A. Let me think! First of all the entire cathode is at a uniform potential and the
second advantages that the heater wires are so close together that the current in them
produces practically nomagnetic field.
B. From my point of view you know both English and Electronics well. If I
were your English teacher I should put you an excellent mark.

rather, indirectly heated cathode, filamentary cathode, physical construction; to

Эта статья довольно трудная. Мне потребовалось много имени, чтобы пе-
ревести ее. В ней говорится об устройстве катодов. Известно, что два вида ка-
тодов используются в электронных лампах. Катод с косвенным подогревом
имеет два преимущества перед нитевидным катодом.
