A FEW UNITS NAMED after FAMOUS SCIENTISTS.

Words lake volt or watt have become part of our language so completely that we sometimes forget that these are the names of famous scientist whose name it bears.

Let us recall a few such units…

An ampere is the unit of electic current in common use. It is that current which, when passed through a solution of silver nitrate in water, will deposit silver at the rate of 0.001118 grams per second. The second unit is named after Andre-Marie Ampere.

A few units named after famous scientists.

A coulomb is a unit of electric charge equal to the quantity of electricity transferred in one second by a current of one ampere. It is named after Charles Augustin de Coulomb.

A farad is a unit of electrical capacitance. It is named after Michael Faraday.

A volt is the difference of potential between two points if one joule of work is required to transport one coulomb of charge from one point to the other. It is named after Alessandro Volta.

THE LAMP

Russian inventors made tremendous contributions to the development of electric illumination.

The first ever man –made electric light illuminated the laboratory of the St. Petersburg physicist Vasily Petrov. The physicist was studying some of the properties of an electric current with the aid of a huge battery of galvanic cells. On November 23 1802 , Petrov had discovered the electric are, a form of the gas discharge.

In 1876 Pavel Y ablochov set to work to invent an are that would burn like a candle, without any adjustment. His work was successful and in 1876 the “Yablochkov candle” was the subject of a report to the

Paris Academy. ЗАДАНИЕ: 1.Прочитайте и переведите текст..

MICHAEL FARADAY

An English physicist was lecturing before an audience in London over 150 years ago about some of the tricks that could be performed with magnets and wires. He had a coil of wire connected to a galvanometer. Since there was no current flowing through the wire, the needle of the instrument was motionless. Then the lecturer lowered a bar magnet into the coil. He removed the magnet. The needle jerked again, this time to the left.

The story is told that after the lecture a woman from the audience approached the lecturer and asked him:”But, Mr. Faraday, of what use is the electricity produced for just a split second by this magnet?”

Very politely, Michael Faraday asked in return, ” Madame, of what use is a newborn baby?”

Notes:

1.Lowered a bar magnet

2.2. For just a split secjnd

DESINGN AND APERATIONS OF OIL LEVEL CHEKING RELAY

The relay comprises a relay unit and a detector which are interconnected by means of a length of a high voltage cable.

The detector is a cylindrical capacitor made up of two nickel plated tubes, one mounted in the other concentrically, separated by dialectical insulation. The outer tube is provided with two lengthwise slots for the passage of oil when in immersed condition.

Operation of the detector is based on the abrupt ehange in the electrical capacitance when it becomes immersed in the oil or Diesel fuel. When air flows between the concentrically arrange tubes of the detector , the average when capacitance in air equals 15-18pF
