Electric Charge and Field

Modeling and simulation of dynamic systems is Pham Huy Hoang Electromotive force (emf) voltage (electromotance): is that which tends to cause current (actual electrons and ions) to flow, is the external work expended per unit of charge to produce an electric potential difference across two open-circuited terminals.

¾ With the modern knowledge about the structure of matter we know that electric charges come from elementary particles: negatively charged electron and positively charged proton. In nuclei there are also neutron with no charge. Interaction between charges: two positive charges or two negative charges repel each other. A positive charge and a negative charge attract each other. This interaction is called the static electric interaction.
