The Basics What is Electrical Current? Answer: Electron Flow Electrical current is the flow of electrons in a conductor. Current is produced when an excited electron from one atom collides with an electron from another atom. This action displaces the electron from its orbit around the nucleus. This electron flow is known as electricity. www .
