If you connect ordinary headphones to the microphone input, they can be used as a microphone. Simplistically, the design of the headphones and the microphone is the same: the membrane is connected to a coil with a wire located in the magnetic field of a permanent magnet. In headphones, during normal use, the current supplied to the coil is converted to membrane vibrations, and vice versa in a microphone.

If you find yourself in a falling elevator, the best strategy to increase your chances of survival is to lie on your back and try to occupy the largest possible floor area. In this case, the impact force will be maximally distributed over the surface of the body. It is widely believed that you just need to jump during a strike, but this is hardly a mistake, someone is able to accurately guess the time of a collision and jump at the same speed as the elevator falls

To look through the glass with a matte surface, just stick a piece of transparent tape on it. Due to the unevenness of the frosted glass, the light is scattered, but the adhesive side of the adhesive tape smoothes out these irregularities, and as a result, the light passes as if through ordinary glass. It should be added that if the surface is matte on both sides, this trick will no longer work.

There is an optical phenomenon that can be called an inverted rainbow, although it happens very rarely. Such a rainbow appears only when several conditions are met. In the sky at an altitude of 78 km there should be a thin curtain of cirrus clouds consisting of ice crystals, and sunlight should fall on them at a certain angle in order to decompose into the spectrum and reflect into the atmosphere. The colors in the rainbow "upside down" are also the opposite: purple at the top and red at the bottom.

A bird sitting on a wire of a high-voltage power line does not suffer from current, because its body is a poor conductor of current. A parallel connection is created at the places where the bird’s paws touch the wire, and since the wire conducts electricity much better, a very small current runs through the bird, which can not cause harm. However, if the bird on the wire touches another grounded object, for example, the metal part of the support, it immediately dies, because then the air resistance is too large compared with the resistance of the body, and all the current goes through the bird.

If the boiled egg is twisted on a smooth surface, it will quickly wrap in a given direction and will rotate for a long time, and the raw one will stop much earlier. This is because a steep egg rotates as a whole, and in a raw one the contents are liquid, weakly bound to the shell.

Knowledge of the designation of the elements of an electric circuit is an important condition for the formation of students' physical literacy. The school physics course offers a whole list of vocabulary words, symbols, formulas, notations for memorizing and writing them.
The interactive simulator is designed to introduce the designation of the elements of an electrical circuit. The work was done on the basis of a template for creating interactive simulators with the “Screen” technology in the Microsoft Office Power Point program, as well as using a template made by N. N. Pokrovkova

These presentations are a small stage of the lesson where the teacher will show the designation, appearance and picture of the element being studied. I have two presentations for two different lessons.

The first radio was completely different from modern radios

The message was transmitted using Morse code.

The first message consisted of only 2 words "Heinrich Hertz"

Heinrich Hertz is a German physicist who experimentally proved the existence of electromagnetic waves. A unit of measurement of frequency 1 Hz is named after him.

“I am proud that I was born Russian. And if not contemporaries, then perhaps our descendants will understand how great my devotion to our homeland is and how happy I am that it is not abroad but in Russia that a new means of communication has been discovered. ” Popov A.S.

Soon, the invention of A. S. Popov began to apply in the Russian fleet

In the wake of Popov was the Italian inventor Guglielmo Marconi. He improved the Popov radio and received a patent for it.

Marconi increased the communication range to thousands of kilometers and organized the industrial production of radios. It was with the help of his radio that the SOS signal from the Titanic was given

In 1909, Marconi received the Nobel Prize for his work in the field of radio communications. A.S. Popov had already died by then.

Years passed, the appearance of the radio changed ...

There were televisions, radars ...

The time has come for radio telescopes, cell phones ...

Modern information technology would not have been possible without the invention of A. S. Popov

Radio Day is our common holiday. Congratulations !!!

Electric current class 8

Electric current is the directional movement of charged particles. In metals, these particles are electrons.

The movement of electrons through the wires is impossible to see, therefore, the presence of current in a conductor can be judged only by its actions on surrounding objects.

The effects of electric current: thermal and light, chemical, magnetic, mechanical.

Thermal action of the current The thermal effect of the current is based on the fact that any conductor through which current flows is heated and gives its heat to the environment. This principle underlies the operation of any electric heating device.

The use of thermal current in everyday life

Light effect of current Light action of current is associated with thermal. If the metal body is heated to a certain temperature, then it will begin to glow. This principle underlies the operation of an electric incandescent lamp.

Chemical effect of current A chemical effect is due to the fact that current passing through solutions and melts of substances can cause a reaction. As a result of the reaction, one of the electrodes will release pure metal.

Application of the chemical action of current Since the mid-19th century, the chemical effect of current has been used to deposit thin layers of silver on a cheaper base.

Magnetic action of current The magnetic effect of current is due to the fact that a magnetic field is created around any current conductor that can affect some bodies.

Application of the magnetic action of current Electromagnets are the main component of electromagnetic cranes, magnetic locks, electric bells, loudspeakers and telephones.

The mechanical action of the current The mechanical action of the current is due to the fact that a force is applied to the coil with the current placed in the magnetic field, which causes the turn of the coil. This principle underlies the operation of all electric motors.

Application of the mechanical action of current Electric motors are most widely used in everyday life, industry, and transport.

The magnetic action of the current underlies the operation of electrical measuring instruments (ammeters and voltmeters).

Thanks for attention. We wish you success in further studying physics!

Energy-saving lamp Ogorodova Valeria 8th class "B"

An energy-saving lamp is an electric lamp with a significantly greater ratio between the luminous flux and power consumption compared to incandescent lamps. Due to this, their use contributes to energy savings.

Types of energy-saving lamps Fluorescent lamps LED lamps

Fluorescent lamp Fluorescent lamp - gas-discharge light source. It consists of a tube coated with a thin layer of crystalline powder - phosphor. The tube is filled with an inert gas or a mixture thereof. A metered amount of mercury is introduced inside, which, when the lamp is in operation, goes into a vaporous state. The tube is hermetically sealed. At the ends of the lamp there are plinths with contact pins for connecting the lamp to the circuit.

Types of Fluorescent Tubes Compact Fluorescent Tubes Linear Fluorescent Tubes

LED lamps LED lamps use LEDs as a light source. LED is a semiconductor device that creates light when an electric current is passed through it.

Key Benefits Energy Saving Weak Heating Longer Service Life Energy Saving Lamp Warranty

Who invented the lamp? The main inventors of incandescent lamps are T. Edison and A.N. Lodygin. But in fact, this invention is the result of the long work of many people, such as P.N. Yablochkov, V.D. Coolidge, D.U. Swan, and many others.

Light emission People have noticed for a long time that metals with strong heating begin to emit light, the color of which depends on the heating temperature. The principle of an incandescent lamp is based on this principle, as was said earlier. RED ORANGE YELLOW BLUE WHITE

First successes The main problem when trying to invent an incandescent lamp was the melting of many metals with strong heating. To do this, the bulb thread had to be created from such metals, the melting point of which is very high. Therefore, the thread of the first lamp (Delarue, 1809) was made of platinum (melting point \u003d 1750), but even this was not enough for normal lighting of rooms. In 1838, Jobard invented the first lamp, using a carbon rod as the filament.

Edison In the second half of the 1870s, American inventor T. Edison conducts research work in which he tries various metals as a thread. In 1879 he patented a lamp with a platinum thread. In 1880 he returned to carbon fiber and created a lamp with a life time of 40 hours. At the same time, Edison invented the household rotary switch. Despite such a short lifetime, his lamps displace the gas lighting used until then.

Lodygin A.N. Lodygin in the 1890s invented several types of lamps with filaments of refractory metals. Lodygin proposed to use tungsten filaments (these are the ones used in all modern lamps) and molybdenum in lamps and twist incandescent filaments in the form of a spiral. He made the first attempts to pump out air from the lamps, which saved the thread from oxidation and increased their service life many times. The first American commercial lamp with a tungsten spiral was subsequently manufactured according to Lodygin's patent. He also made gas-filled lamps (with carbon filament and nitrogen filling).

Modern lamps In modern incandescent lamps, the thread is made mainly from tungsten. The bulbs of these lamps are filled with heavy gases, which many times increases the light output (in the first lamps there was a vaakum). Incandescent lamps have changed a lot in their history and experienced a lot, it is possible that soon humanity will invent new types of lamps that will displace modern ones.
