electric charge [ imenica {elektrotehnika} ]
Generiši izgovor

Property of some bodies that causes them to exert forces on each other. Two bodies both with positive or both with negative charges repel each other, whereas bodies with opposite or “unlike” charges attract each other, since each is in the electric field of the other. In atoms, electrons possess a negative charge, and protons an equal positive charge. The SI unit of electric charge is the coulomb (symbol C) .
Electric charge can be generated by friction induction or chemical change and shows itself as an accumulation of electrons (negative charge) or loss of electrons (positive charge) on an atom or body. Atoms have no charge but can sometimes gain electrons to become negative ions or lose them to become positive ions. So-called static electricity, seen in such phenomena as the charging of nylon shirts when they are pulled on or off, or in brushing hair, is in fact the gain or loss of electrons from the surface atoms. A flow of charge (such as electrons through a copper wire) constitutes an electric current; the flow of current is measured in amperes (symbol A).
