I believe in exploring new ways to understand the subject better

The free electrons in a conductor move with random velocities and in random directions. When an electric field is applied across the conductor the randomly moving electrons are subjected to electrical forces along the direction of the field. Due to this field, the electrons do not give up their randomness...

The free electrons in a conductor move with random velocities and in random directions. When an electric field is applied across the conductor the randomly moving electrons are subjected to electrical forces along the direction of the field. Due to this field, the electrons do not give up their randomness of motion, but they will be shifted towards higher potential with their own random motion. That means the electrons will drift towards higher potential along with their random motions. Thus, every electron will have a net velocity towards the higher potential end of the conductor and this net velocity is referred as the drift velocity of electrons. Hopping, you understand the definition of drift velocity. The current due to this drift movement of electrons inside an electrically stressed conductor, is known as drift current read less
