Electricity and Electromagnetism are two branches of physics. Electrical and magnetic phenomena began to study towards the end of the 18th century, when in 1785 French physicist Charles de Coulomb confirmed that the force of attraction or repulsion power is directly proportional to the product of the masses and inversely proportional to the square of the distance that separates them. This was referred to as the Coulomb law. very low frequency, however, were the mathematicians Simeon Denis Poisson and Carl Friedrich Gauss who came to the conclusion that two particles with opposite charges attract, speeding toward each other. From here comes the classical theory of a simple circuit (journey or an electric current path), which posits that the two poles of a battery have loads opposite (positive and negative). When these poles are connected from a conductor, negative particles are attracted to the positive pole, by heating the driver, issue that happens because it offers resistance to movement. When the particles reach the positive pole, are forced to navigate inside the battery to the negative pole, against the forces who oppose this (Coulomb’s law).
