Explanation
Electric power is transformed to other forms of power when electric charges move through an electric potential (voltage) difference. When an electric charge moves through a potential difference, from a high voltage to a low voltage, the potential does work on the charges, converting the energy in the potential to kinetic energy of the charges, or some other form. This occurs in most electrical appliances, such as light bulbs, electric motors, and heaters; they consume electric power, converting it to mechanical work, heat, light, etc.
If the charges are forced to move by an outside force in the direction from a lower potential to a higher, power is transferred to the electric current. This occurs in sources of electric current, such as electric generators and batteries.

Famous quotes containing the word explanation:
“There is a great deal of unmapped country within us which would have to be taken into account in an explanation of our gusts and storms.”
—George Eliot [Mary Ann (or Marian)
“Auden, MacNeice, Day Lewis, I have read them all,
Hoping against hope to hear the authentic call . . .
And know the explanation I must pass is this
MYou cannot light a match on a crumbling wall.”
—Hugh MacDiarmid (1892–1978)
“There is no explanation for evil. It must be looked upon as a necessary part of the order of the universe. To ignore it is childish, to bewail it senseless.”
