Question

When electrons drift in a metal from lower to higher potential.does it mean that all the 'free electrons of the metal are moving in the same direction?​

◆By no means. The drift velocity is superposed over the large random velocities of electrons.

Answer 2

No they are actually moving in the same direction like straight line but the net movement will be from lower to higher potential. Electron has two motions

1: drift motion due to potential difference.

2: normal motion of the electron in a metal when there is no potential is maintained.( Random motion)

So the electron experiences combination of these two motions.

Look at this picture
