The phenomenon of giving or receiving an electron becomes an electric charge. When an electron receiver becomes a negative electron. When the donor becomes a positive electron. Electric charge is the property of subatomic particles, which appear as well as interact with the electromagnetic force, one of the four fundamental interactions of nature. The charge is derived from the atom, in which the electrons and protons in the nucleus carry a charge. It is a conserved quantity, meaning that the total charge of an isolated system is always constant regardless of any changes taking place in that system. In the system, charges can be transmitted between objects, either by direct contact, or by transmitting objects, such as wires. The term electrostatic refers to the presence (or imbalance) of an object's charge, which usually occurs when the material is rubbed against each other, resulting in the transfer of charge from one object to another.
Current occurs when there is movement of charges, with the intensity of the current being measured in ampere. Electric current can contain any kind of moving charge, which is usually seen as an electron, but any moving charge produces current. For historical reasons, the positive direction of current is defined as having the same direction of movement of the positive charges contained in it, or the direction of propagation from the positive part of the circuit to the negative. Current defined in this way is called conventional current. In electronic circuits, the positive direction of current is the opposite direction of the movement of electrons in the circuit. However, depending on the conditions, the current may consist of the flow of charged particles in either direction, or even in both directions at the same time. The positive and negative dimensional convention is only for simplification in cases.
