electrical field




Introduced this concept
English chemist and physicist
(1791 - 1867 AD)
Michael Faraday

Affect the strength of the electric field between the two shipments in the same way they affect the gravitational force between two masses. But the electric field is slightly different. The force of gravity depends on the mass ofobjects, while electric power based on a charge objects. While it couldattract attraction towards each other only two blocks, electric power can be a powerful attraction or repulsion. If the shipments in the same reference(for example: both positive), there will be repulsion force between them. Ifthe shipments there will be a different force attraction between objects.Commensurate with the amount of force inversely to the square of the distance between objects, as directly proportional to the product of the amount of shipments
