Even the unit of rc cars electric charge of a body charged by friction as electrons is already a very high number. For all practical units that were developed for both the amount of electricity or electric charge electric current to these units giving the name of several scientists who worked with electrical phenomena. The practical unit of electric current is the Ampere and is equal to one coulomb per second. To simplify the notation using letters to represent different concepts and units. The electric current I is represented by a unit and its an A. A unit of time is represented with lowercase "t" (because capital reserves for the temperature T) With these representations we can write the current dynamic electricity. The dynamic electricity occurs when there is a permanent source of electricity that causes the permanent circulation of electrons through a rc cars conductor. Permanent sources of electricity are divided into chemical and electro. Battery An electric battery is a chemical source of electricity. Within the stack are generated chemical reactions resulting in the production of electrons. These electrons are available for running on such a driver, but unlike a charged body the source of electrons is not exhausted. A dynamo is a machine that converts mechanical energy electromechanical rotation into electrical energy. Does the same as the stack, i.e. the two bodies can assimilate loaded with different polarity where circulating loads are replaced as they are taken. In this case the energy needed to restore the rc cars battery load is removed from a magnetic interaction between electrons and the rotating magnetic field of the dynamo. With the dynamic power up to another concept which is the ability of a generator to produce a constant current flow. What determines the electrical current flowing between two charged bodies? It depends on the charge difference between these bodies and the type of bar with which to interconnect them. Actually, it is not necessary that one of the bodies is negative and one positive. If one is very full of electrons and the other only has a small excess of electrons and connected to a bus bar, it will balance the load so that both bodies will after a while an average number of electrons. We can say therefore that the current flow depends on the difference in rc cars electrical potential between the two bodies (the more loaded this body than the other) and the type of rod used to establish the connection between the bodies.
