Learn how to determine the value pet support conductor.

1. THEORETICAL INTRODUCTION.

If along a metal conductor, which is a closed lance, a strum flows through, then by the force of the strum I at the conductor and the voltage on the yoke U is directly proportional to the fallow, which Ohm's law , To say that the strength of the struma in the conductor is directly proportional to the pressure on the yogic ends and is wrapped in proportion to the yogic support:

The value R is called electric support or simply a support of the conductor. In the same way, by rubbing in the mechanics I create the protidium of the body and bring it to the transformation of the mechanical energy into the internal energy of the body, the opir of the conductor characterizes the protidium of the struma in the conductor, as it is enchanted by the internal conductor of that haotic

Opir of the lancer's vineyard is tensed on this tract, which is necessary for moving into a new stream, which is a healthy one.

In CI, Om is taken for a single support. The ohm is the opir of such a conductor, which is a stream of 1 A at a pressure of 1 V. The opir of the conductor is deposited in the material of the conductor, so that it becomes a crystal lattice, and also it forms and expands. For a homogeneous cylindrical conductor (droid), the length and area of the transverse section S opir is assigned to the formula:

The value that characterizes the fallowness of the support of the conductor in terms of material, for which wine is crushed, and in the form of better minds, is called support speeches.

One pet support in СІ є 1 Ohm.

From formulas (2) and (3) it is possible to take a working formula for assigning the value by the last way:

(4)

If the conductor may have a cylindrical shape, then the area of yogo cut is determined by the formula, de d- Wire diameter.

Then the residual working formula will look in the future:

2. HID ROBOTS.

1. Choose a lansy for an offensive scheme:

2. Measure with an ammeter 5 the value of the force of the stream flowing through the follow-up opir R and with a voltage voltmeter on the yoke.

3. By changing the rheostat opir R1, the force of the strum and the tension, take another 6 value of the strum and the tension.

4. Calculate for the formula (5) the value of the strength of the struma and the tension for the skin steam.

5. Appreciate the speech, for which the explorer is crushed (div. appendage).

6. The results of the simulation and the calculation should be entered in the table.

7. Zrobiti visnovok about vikonan robot.

In tables right- The number of subdivisions, on the yak the arrow of the ammeter or voltmeter was on the yak at the time of the count.

The topic is called: Electric Opir conductor. What is it. I will try to refresh your knowledge (for someone who has forgotten) and reveal secret information (for those who do not know) about it simpler, more basic and universally more understandable.

As you know, our world has its own protidium. For example, on a car that is collapsing, there will be a lot of force rubbing (about winding, about the surface of the road, rubbing internal parts, etc.), when heated, be it an object on a new shoe, you will pour in a lower temperature dovkilla, as soon as the heating is applied, turn the object to an excessive temperature. The sphere of electricity has a similar influx (one hundred percent electric struma) will repair the electrical opir.

The electrical opir of the conductor, the purpose of the construction of materials (more precisely, the speeches from those and the conductor itself was broken) against the charge of charging particles of the middle conductor. Moreover, it should be noted that it is necessary to convert electric energy into another form (importantly, electricity is converted into heat).

The electric opir may be alone in the world under the name "Om". 1 ohm - tse opir, which is a matimeste of mercury with height - 106.3 cm; cross sich. - 1 sq. mm. and the temperature is 0 degrees. Opir is usually denoted by the letter R or r. Name the values of the support: Ohm, kOhm (1 kiloohm \u003d 1000 Ohm), mOhm (1 megaohm \u003d 1000000 Ohm).

In order to better understand the essence of the support (like and through what it is blamed), we should guess the school lessons of chemistry and physics, on which we told about the structure of speeches. Solid speech is impersonal atoms (molecules). The stench is mіtsno pov'yazanі mіzh themselves by fields and utvoryuyut structure like a crystal lattice. Near the skin atom (behind the yogo orbits) electrons wrap around. Electronics, which have been scattered far from the atom, are built up and transferred to the atomic atoms. Such electronics are called free and sound materials (conductors) can conduct an electric stream through themselves.

When connected to a call fast dzherel Electricity (electric field) in order to start moving from one end of the conductor to the next. Yakby didn’t care about anything during their displacement, then it can be said about the conductor that it can have zero support (the superconductivity of the same materials at low temperatures = -273 degrees). At normal temperatures, electrical conductors make a number of transitions for the passage of electronics, zvіdki and vinikaє tsey electrical conductor conductor.

What gives rise to it pouring into the electrical opera? It's not surprising, however, that the atoms themselves, the shards of stink and the electrons on their way. Electron, which rushes on a great speed, constantly has to run into atoms, while expending its internal energy, as if, in its own line, transforms into heat. Otzhe, scho dovsha way (providnik), then more in the new internal opera. Chim more stretch conductor, then navpaki, the electrical opir yogo will change (more electronics will pass through it).

Oskilki at different materials(rechovins) different structures of crystal lattices, also, and opir stinks will be the same. It is also called a pet support for the material. Tobto, pitomy opіr, the value of the electrical support is exactly the same as the singing material (conductor), with a length of 1 meter and a transverse band of 1 sq. mm. Pitomy opir is denoted by the letter "p". Below is the table of the pet support of the conductors.

For rozrahunku electric support sevno ї dovzhiny and perezіzu that chi іnshoy material vikoristovuyut the following formula: R=p*L/S

R = electrical opir;

p = reference to the material;

L = Conductor's length;

S = cross section of the conductor.

Slid (ale not obov'yazkovo) vrakhovuvaty, scho values of temperature vplyvaє on the hot electric opіr of the conductor. When the conductor is heated, a new one sees an increase in the chaotic fluctuation of the atoms of the speech. Tse in his line stows the passage of electrons through the conductor, which is the most important source of material. With a simple (special accuracy is indispensable) rozrahunka electric support, sound the temperature is not protected, oskolki її pouring in insignificantly. Approximate value of the temperature fall on the opir: 0.4% per 1 degree.

On which I will complete the topic: Electric conductor conductor. What is it.

P.S. Irrespective of those that are not the best conductors of an electric stream (it was possible to conduct electricity more quickly), they are widely stosuvannya wised by the cheapness of that great abundance of nature.

As you know, our world has its own protidium. For example, on the car, which is collapsing, the force is rubbing (about the wind, about the surface of the road, rubbing the internal parts, etc.), when heated, any object on the new shoe will add a lower temperature of the navkolishny middle, as if the heating was applied , turn the object to the front temperature. In the field of electricity, there is a similar reverse inflow (a hundred times the flow of an electric stream) repairing an electric opir.

With the connection of a stable, stable electrical supply (electric field), it is possible for the electrons to move in order from one conductor to another. Yakby didn’t care about anything during their displacement, then it can be said about the conductor that it can have zero support (the superconductivity of the same materials at low temperatures = -273 degrees).

Electron, which rushes on a great speed, constantly has to run into atoms, while expending its internal energy, as if, in its own line, transforms into heat. Otzhe, the former path (provider), then more in the new internal opera. The larger the span of the conductor, then, on the contrary, the electrical opir yogo will change (more electronics will pass through the new one).

Oskіlki in different materials (rechovins) of different structures of crystalline gratings, also, and opir they will be different. It is also called a pet support for the material.
