Condenser, device and purpose
The capacitor is a device that allows you to accumulate a significant charge and energy of the electric field. This radio electronic component is structurally similar to a sandwich in which there are two conductors and a dielectric. As a dielectric, a vacuum, a liquid, a solid, and, of course, a gas is used. This term is translated from Latin, as a “sealer”, “thickener fluid.” After all, in those days when the prototype of a condenser was invented, scientists thought that an electric current is a liquid.
This is a two-pole element having a definite/variable capacitive value, low conductivity. The capacitor is a passive electronic element. The first remaining of it was in the middle of the eighteenth century. It was a jar of glass, which was wrapped in foil, covered with a lid of wood. In this cover 2 bars of metal had been stuck, and attached to an electric current generator. This primitive condenser was called by the name of Professor Mushenbrock from Leiden-“Leiden Bank”, because some scientists consider him the father of the invention. But in principle, even two centuries before the professor, experiments with electricity through a primitive condenser were conducted by the prelate from Germany, Evard von Kleist. In one, all the scientists agree that after all, the device, similar to the modern condenser, appeared in October 1745.
The element was improved over the years, and beginning from the middle of the nineteenth century it was not everywhere, but capacitors began to be used in engineering. The beginning of the twentieth century was marked by the opening of production plants for the production of condensers.
Today, capacitors are necessary in the manufacture of any kind of equipment.
Modern application of capacitors in industrial sectors
Practically there is no such sphere where this useful component would not be used, it is possible to say, the condenser has conquered the world.
- Television, radio equipment, equipment;
- Radar, telecommunications, telephony;
- Manufacture of devices and equipment for civil and military industries;
- Exact instrumentation – computers, smartphones, laptops, measuring equipment;
- Laser instrument making and many other industries.
The most unusual edible condenser
Not so long ago, in America (Arizona University), the scientists created an absolutely unusual capacitor, a real sandwich. All the necessary “details” were bought at an ordinary grocery store. The composition of this, as it was called “edible” condenser, includes cheese, activated carbon and energy drink. According to the creators themselves, such a device will give the necessary energy to medical devices, and most importantly, it will help fighting “bad” bacteria. All the data on the invention was published and described by the journal Advanced Materials Technology, and Discovery Channel.
In an edible condenser, this energy drink acts as an electrolyte. A strip of algae, impregnated with an energy drink, was clamped between polar charged electrodes. Electrodes are also edible, because they were made from the mix of crushed coal, raw egg and gelatin. To enhance the electrical conductivity, the outer layer is made of cheese. Scientists say that such a condenser has a high specific electric capacity. During the tests, the device was charged and allowed to work with a video camera and LEDs. After the experiment, the scientist who presented the device, bit off a piece of it, chewed it, swallowed, thus proving the edibility of the condenser.
It was also proved that the device is able to kill the colon bacillus by electricity, without harming the human body. It turned out that the condenser “works” in the stomach for 4 minutes, and then dissolves under the action of gastric juices.
Such an “edible” device in will replace some medical devices that are forced to swallow patients for diagnostic purposes.
