      2.7.6 Translate the word-combinations

transmission lines, current path, current source, additional charge carriers, filamentary
transistor, point-contact transistor, boundary layer, metallic point contact, carrier
concentration, current cross section, majority carriers, minority carriers, such a
modification.

      2.7.7 Answer the questions

1. What is the transistor inended for? 2. What may we refer to in the discussion of its
mechanism? 3. What happens to a switch when a weak current arrives over a long
transmission line? 4. What varies the conductivity in a current path of a local current
source? 5. How do the various types of transistor s differ? 6. When have we the
filamentary transistors? 7. What happens if the affected current path is a p-n junction?
8. How does the unipolar transistor operate? 9. How is this type of transistor
restricted in contrast to the other types?

      2.7.8 Form nouns from the following verbs

amplify, conduct, apply, vary, inject, intensify, transmit, restrict, occur.

      2.7.9 Translate the conditional sentences, define their types. Translate
provided as a conjunction

1. Provided we got the necessary devices we should check this apparatus. 2. A cell
supplies electric energy provided its electrodes are of different materials.

      2.7.10 Translate the sentences, mind the functions of the infinitive

1. The device to be used here is intended for the amplification of electrical signals.
2. One can use a switch to start or to block the strong current from a local source. 3.
The most modern equipment to be used at this station is the most up to date. 4. One
can see that these types of machines to be described here differ slightly from
previous ones.

      2.8 Part 8

distinguishable, intrinsic, contribute, mutually, sign, excess, analogous, reciprocal,
extrinsic, consumption.


      2.8.2 Read the words, pay attention to stress shift

apply — application; active — activity; limit — limitation; particle — particularly.
