WebCurrent is the rate at which charge flows through a surface of any size — like the terminals of a battery or the prongs of an electrical plug. Intensity is the average power per unit area transfered by some radiant phenomenon — like the sound of a busy highway, the light from the Sun, or the spray particles emitted from a radioactive source. WebElectrical current is the rate of flow of electric charge. When current flows, electrical work is done and energy transferred. The amount of charge passing a point in the circuit can …
