A Few Words About Electron.

 

The tiny electron discovered by J.J.Thomson as you already know is the giant in modem times. Thomson's discovery paved the way to many exciting new discoveries. Scientists are moving forward towards a better understanding of its laws. Electrons do wonderful things in calculating machines, which besides working hundreds of which besides working hundreds of times faster than any human calculator, can hear, see, feel, touch. It is hard to imagine how we could calculate without using electronic calculating machines. More and more often we hear of scientists' using these machines in new fields. With the help of electronic calculating machines the scientists succeeded in reading the language of an ancient people of Mexico.

II

During the past twenty years significant gains have been made in the fields of science, industry and engineering. Change and growth require rational decisions. The latter demand that reliable data be obtained instantly and be transmitted rapidly. The period of the 1960's has been an extraordinary decade.

The advancement of technology has brought man to the outer limits of the known Universe.

The growing demands for instant data have resulted in the invention of the electronic computer.

Computers are information handling machines. Computers handle large amounts of information rapidly and precisely. When a satellite is launched, thousands of computations are made with the help of computers.

The system for processing records makes maximum use of the automation. Manual (ручной) operations are replaced by those that require little, if any. (почти не требуют) human assistance.

Life is now unthinkable without electricity. Technical progress in any country is dependent to a high degree on producing electric energy. Great progress was achieved in generating electricity in our country. The scientists are looking for the most efficient ways of getting electricity on a wide scale. Not long ago they succeeded in designing special reactor for the Beloyarskaya Station. This atomic power station is the first in the world, where the so-called nuclear steam superheating up to 500°C was employed. The scientists and engineers at the station. now engaged in creating the power unit with a fast neutron reactor capable not only of generating electricity but of producing nuclear fuel as well. Every kilogramme of uranium used in this new reactor will yield 1.5 kilogrammes of new fuel.

IV

Conductors.

Conductors are materials having a low resistance, so that current easily passes through them. The lower the resistance of the material, the more current can pass through it.

The most common conductors are metals, and silver and copper are the best of them. The advantage of copper is that it is much cheaper than silver. Thus, copper is widely used to produce wire conductors. One of the common functions of wire conductors is connecting voltage source to a load (нагрузка) resistance. Since copper wire conductors have a very low resistance a minimum voltage drop (падение) is produced in them. Thus, all the applied voltage can produce current in the load resistance.

Most materials change the value of resistance when their temperature changes.

V

Capacitors (Конденсаторы)

A capacitor is one of the main elements of a circuit. It is used to store (хранить, накапливать) electric energy. A capacitor stores electric energy provided (при условии) that a voltage source is applied to it. The main parts of a capacitor are metal plates and insulators. The function of insulators is to isolate the metal plates and in this way to prevent a short (короткое замыкание). There are two common types of capacitors nowadays: a fixed capacitor and a variable capacitor. The plates of a fixed capacitor cannot be moved, for the reason (по этой причине) its capacity does not change. The plates of a variable capacitor moving, its capacity changes. The greater the distance between the plates, the less is the capacity of a capacitor. Variable capacitors are commonly used by radiomen; their function is to change the frequency in the circuit. Fixed capacitors are applied in telephone and radio work. Fixed capacitors have insulators produced of paper, ceramics and other materials, variable capacitors have air insulators. Paper capacitors are commonly used in radio and electronics; their advantage is their high capacity.
