Electric current is the flow of electric charge through a material. It is a measure of the amount of charge passing a point in a circuit per unit of time. The unit of electric current is the ampere (A), which is the flow of one coulomb of charge per second.
Electric current can be caused by the movement of electrons, protons, or ions in a conductor or semiconductor. In a metal conductor, such as a copper wire, the movement of electrons is responsible for the flow of electric current. In an electrolyte or a solid-state ionic conductor, such as a battery, the movement of ions is responsible for the flow of electric current.
Electric current can be either direct current (DC) or alternating current (AC). In DC, the electric charge flows in one direction, whereas in AC, the electric charge changes direction periodically. The majority of household appliances and electronic devices use AC, whereas batteries and certain types of motors use DC.
In summary, Electric current is the flow of electric charge through a material, it is measured in ampere (A), it can be caused by the movement of electrons, protons, or ions in a conductor or semiconductor, and it can be either direct current (DC) or alternating current (AC).
