what is current?

Electricity is the flow of free electrons in a conductor from one atom to the next atom in the same general direction. This flow of electrons is referred to as current and is designated by the symbol I.Electrons move through a conductor at different rates and electric current has different values.

Current is determined by the number of electrons that pass through a cross-section of a conductor in one second.  Current is measured in amperes which is abbreviated  as amps.The symbol for amps is the letter A.
