It is extremely relevant that among the existing electrical particles, gravitational forces of attraction can be identified by their masses and electric forces due to their electric charges. Therefore, gravitational forces should not be considered, since the mass of a particle is minimal. In the case of an equality or balance of charges in a body, it can be said that it is electrically neutral, without a net load so that it can interact with other bodies. A body must be electrically charged in case it has a reduced amount of unbalanced load or liquid load.
The electric charge refers to a physical property with the purpose of determining the electromagnetic interactions. This charge is stored in large quantities in the bodies, although the perception of it does not happen easily. It should be emphasized that there are two types of load, positive and negative, that if they are in equilibrium, become completely imperceptible mrosupply ac motors. Electrically charged objects interact by exerting forces of attraction or repulsion on one another. The unit of measurement of the electric charge greatness in the International System of Units is the coulomb, represented by C, in which it was named in this way in homage to the French physicist Charles Augustin de Coulomb.
