What is Electric Current? Definition & Direction of flow of current

Electric current is the essence of electrical science, and it represents any movement resulting from electric charge carriers, and in electrical circuits is the rate of flow of charges through a specific point inside the circuit, so that these charges are either negatively charged electrons, positively charged protons, positive ions or holes, and in the conductor wire, the electric current is a measure of the amount of charges flowing through a specific point in the wire per unit time, and these charges are electrons.
 Electric current is defined as the flow of electric charges through an electrical conductor, and the charges are either electrons, protons, or ions, and it is measured in the ampere unit.
 Among the most important properties of electric current that cannot flow without it are the electric potential difference and electrical resistance, from which Ohm's law was derived to calculate the electric current, which is the electric potential difference divided by the resistance.

Electric current is applied in many electrical applications, such as: electric heater, mobile phone, computer, large electrical network system, or any remote sensor node in which electric current is the basis for its operation, and the flow of electron charges through the electrical circuit varies with voltage, so it was derived The special mathematical formula for electric current from Ohm's law, which represents the ratio of electric current with potential difference and resistance across a conductor, and it is as follows
