Thread: direction of electrons, while applying an e.f. to a metal

if we applied an electric field to a metal,
why the direction of electrons is to be in the opposite of the direction of the electric field intensity ()?

And, any animation or image can describe that in a better way ?

It is simply due to the convention that segregates charges into positive and negative with the electron being negative. Look at the Lorenta force equation:

X. The term times the E field, in the absence of a magnetic field causes the force to be directed opposite to the field for a negative charge .

Thanks !

That what i needed.
