Another Russian scientist Yablochkov made a great contribution to the development of electrical science. It was Yablochkov who created the principle of a transformer.lt is he who found the first practical application of the electric arc.
Thanks to Lodygin's great discovery, an electric lamp lights up our rooms.
Popov transmitted signals by means of electromagnetic waves and gave the world his great discovery - radio.
It is Lebedev who discovered and measured the pressure of light. The photoelectric effect was among the numerous discoveries of the famous Russian scientist Stoletov.
However, it is impossible even to list here the great inventions and discoveries that our scientists made in various fields of science and engineering.

Radio was invented in Russia. The world’s first receiver was constructed in 1895 by the great Russian scientist Alexander Popov. There were no transmitters then, therefore his receiver could only pick up signals produced by lightning discharges during a thunderstorm. A. Popov demonstrated a device called a “storm indicator” at a meeting of the Russian Physico-Chemical Society in St. Petersburg on May 7, 1895. This day is marked now as Radio Day.
The meeting was held at British mathematical Society in St. Petersburg.
The world’s first receiver was constructed in 1895 by Morse.
The device demonstrated by Popov was called a telephone.
At the end of the 19th century transmitters didn’t exist.

Electricity is the power that has made possible the engineering progress of today. In fact, electricity has always been with a man, but only within the last few centuries he has learned to apply it.
One hundred years ago there were neither electric lamps, nor electric motors, nor telephone, nor radio. Now electricity is everywhere. We use electricity in our homes and in buildings where we work or study. Electric lamps light our rooms. The uses of electricity in our homes do not end with producing light. How many electric motors are working in our homes! Electric motors operate washing machines, refrigerators, vacuum cleaners, fans, clocks, and other electrical appliances.
Hundred years ago people lit their homes with electric lamps.
There exist refrigerators without electric motors.
Computers operate washing machines.
it is impossible nowadays to live without electricity.

Alexander Popov found a way of trasmitting Morse code signals. In 1897 he sent the world’s first wireless telegram over a distance of 600 m and four years later the range of transmission was increased to 150 km. Ever since, thanks to the work of many scientists of the world, the methods of transmission and reception have been constantly improved. Nowadays radio communication has no limits.
Popov also received Morse code signals.
Only Russian scientists improved the methods of transmission and reception.
There are some limits in radio communication.
The range of the first telegraph transmission was 600 m.

A lot of people began to see how electro-magnets could be used to send messages. One of the most famous people of all in communication is Samuel Morse. He invented the Morse code. This code is still used in signalling all over the world. His idea was simple. He thought of using time, sending current along a wire for a long time or a short time. Combining different sets of these “impmses”, just using the long or short, he made a code for the whole alphabet, and the numbers from 0 to 9.
S. Morse made a code only for the alphabet.
One of the most famous people of all in communications is A. Popov.
Many years ago electro-magnets could not be used to send messages.
The Morse code is now used in signalling all over the world.
