In the event a ball that is similar charges, it is found to repel the first: the charge acts to shove on both balls. This discovery led to the famous axiom: like-charged objects repel and opposite-charged things bring.
Study suggests that the source of charge is from particular types of subatomic particles which might possess the property. Electric charge gives rise to and interacts with each of the electromagnetic force, one of the four fundamental forces of nature.
The charge on electrons and protons is opposite in sign, so several charge may be expressed as being either negative or positive. The proton has a charge that is equal and opposite, and so 1.6022*10-19 coulomb.

Chief post: Electric current, The movement is called an electric current, the power of which is usually measured in amperes. Current can consist of any proceeding a current, although commonly these are electrons is made up by any charge in motion.
Historic convention, a positive current defined as getting the exact same direction of flow as to any positive charge, or the negative part to stream in the positive part it contains. Current defined in this manner is called conventional current. The positive-to-negative convention is widely used to simplify this instance.

The process where electric current passes through a material is termed its own nature changes, and electrical conduction with that of the material whereby they might be going in addition to the energized particles.
