What is an electrophorus?
Electroforus is a form of a primitive static electrical charging battery or generator that was originally invented in 1762 by Swedish physicist Johan Wilck, yet the device function is so basic that it can be made of various common materials. The well -known political character and inventor in colonial America, Benjamin Franklin, popularized this idea by producing one of the wood, sulfur, wax and tin metal. The conventional electrophorus consists of an insulation plate, usually made of resin or plastic of a type on which a metal conductive plate is located. In the middle of the metal plate, another insulating medium is attached, such as a plastic cup used as a handle to prevent premature drainage of the electrophor. Static electric charges can be pulled out of the device by physical touch to the metal plate, whether they charge bulbs for a moment or for other experiments.
The basic principle of electrofor operation is the principle effect of triboelectric effect, otherwise known as stored static electricity. The insulating board is first charged with a static electric charge before the electrophorus is assembled by wiping it on other materials such as a wool that causes an electrical charge in the insulating valve by the electrostatic induction process. Once the insulating plate and the conductive plate are placed together, the static charge in the insulator separates positive and negative charges in the metal conductor. Positive charges in the metal are attracted towards the insulation plate and the negative charges are discouraged.
Induced negative charge on the upper surface of the metal plate can then be released by establishing physical contact with metal and completing the perimeter through the human body to the ground. The charge is often strong enough so that the harmless spark jumps from the metal to the front of the contact or the wires of the small bulb can be placed between two surfaces to temporarily light up as soon as the charge is scattered, the wires of small bulbs. The large version of the Electroforus also lights up the tube -shaped bulb for a moment, afterWhich end is held in hand and the other is held close to a charged metal plate.
One of the unique aspects of the electrofor that makes it a popular demonstration of electrical principles is that the insulating board acts similarly to more sophisticated capacitors or electric storage units in common electronic circuits. Unlike typical capacitors, however, the insulation board holds the charge that is not exhausted by the process of static discharge in the metal plate. After the polarized release of the metal plate has been discharged, if the metal plate is removed from the proximity of the insulation plate, then it is re -placed on the top, the metal is repeated in the metal because the insulator still holds its charge.
This process seems to demonstrate the idea of free energy coming from nowhere, because the static charge is constantly renewed and discharged regardless of how many times the metal plate is removed and then placed back to the top of the insulation plate. In fact, energy is preserved because the workThe physical movement of the metal plate gone and then replaced by potential energy into an electrophoring system, which is then converted to kinetic energy when a discharge or spark. Large versions of the electroforus are known as Van de Graaf generators capable of producing electrostatic voltages in the range of up to 2,000,000 volts, such as the American physicist Dr. Robert van de Graaf alone in the early 30 years.
