ELECTRONIC EQUIPMENT

Hundreds of electronic equipments are now available to science and various industries help to do jobs better or more economically or to take over jobs that could not be done otherwise.

The application, use, and proper maintenance of the many electronic types of equipment now in industrial use demand certain knowledge to be of the fundamentals of various standard electronic equipments.

We already know that in motors, incandescent lamps, transformers, etc., the electricity always flows in the copper wire or other metal parts. But consider lightning, where electricity seems to jump through space. The great electric pressure of lightning forces the electric current to pass through the air. In the same way, inside any radio tube, tiny electric currents are made to pass through the space separating certain parts in the tube. Such action where electricity appeal's to flow through space instead to being confined to metal conductors or circuits is said to be electronic.

Why is it called electronic? Years ago, scientists who were trying to explain how electricity passed through space, imagined such an electric current to be a steady stream of tiny electrical particles. They called these particles electrons. Today, any electric current is believed to consist of countless number of electrons. Only when electricity passed through space, when the stream of electrons comes out of the metal into the open, is such action said to be electronic. A device is called electronic; electricity must flow across the space inside the device and be controlled by that device.

In ordinary air, electrons can be made be jump through space only by pressure of high voltage. But if it enclosed in a tube from which the air has been removed, the electrons flow across the space more easily. All tubes must be carefully sealed for the desired conditions to be maintained inside the tube. Most of the small tubes are vacuum tubes, the large ones usually containing mercury or other vapour.

Some electric lights are electronic. The common incandescent light bulb is not considered as electronic though it is enclosed like a radio tube, for the electric current flows entirely within the metal filament. In contrast, the fluorescent lamp is electronic, its light is produced by the action of electric current flowing through the space between the two ends of the lamp.

Electronics as a science is not new, for radio, sound picture fluorescent light, etc. are known to depend upon electronics.

SUPERCONDUCTIVE ELECTRIC CABLE

 

A superconductive electric cable was made by the research workers at the Power-Engineering Institute. It is a very useful device and its main property is its being cryogenic. Compared with other types of cables, it has a great advantage its use will result in transmitting current practically without losses, which is of great importance since nowadays percentage of losses in transmitting electronic power over long distances is rather high; it is ten percent and even more.

The properties of the new cable being unique, electric current up to 10.000 amp at 10.000V and more can be transmitted over long distances. The superconductive cryogenic transmission lines are especially efficient for Russia: the power resources of the country are known to be concentrated mainly in the eastern parts of the country while three-quarters of the industrial potential are concentrated in the European part.

 

V. Translate the text into Russian and define the tense and voice of the Verbs.

1. We want you to take into consideration that voltage, resistance and capacity are the three important properties to influence the flow of current in an electric circuit. 2. Among the possible sources of power for engines one has to consider the possible of applying atomic energy. 3. If the same cyclotron is to be used for the acceleration of different particles, the necessary adjustment may be made in two ways. 4. This device does not seem to operate because the voltage in the circuit is small. 5. We watched the operator solve a number of complicated problems by using a computer. 6. There are many factors to be taken into consideration when designing a spaceship.
