    The electric field E = potential difference V / length of conductor L. So drift velocity becomes half of its previous value. "When length is doubled, the drift velocity is halved and the resistance is doubled. Thus, when the length of the conductor is doubled, the drift velocity is halved.

    Optical fibre, the name itself suggests that it is a special fibre relating to the transmission through optics (light).
    These made up of glass (silica) or a plastic polymer and their diameters are slightly more than the diameter of a human hair.
    It is best used for transmission of huge amount of data over a long range of distance at a very high rate.
    Optical fibres are more preferred over metal wires as there is less amount of energy loss in transmission with the optical fibres.
