    Answer:

    The difference between P-N junction diode and extrinsic semiconductor is the allowable direction of flow of current

    The extrinsic semiconductor can allow current to flow in both directions while the P-N junction diode permits only a unidirectional flow of current

    Explanation:

    A semiconductor is a substance that has an intermediate conductivity between that of conductors and non conductors

    Examples of semiconductors  include germanium and cadmium selenide

    A semiconductor to which impurities has been added (an activity known as doping) is an extrinsic semiconductor

    Based on the functioning of a semiconductor, doping result in the formation of one of two types of semiconductors including;

    1) N-type semiconductor that has an extra electron and the charge carriers are electrons

    2) P-type semiconductor that has one less (-e⁻) electron and holes are the charge carriers

    An extrinsic semiconductor can conduct allow the flow of electricity in both ways

    A P-N junction diode consists of both the P and N-type extrinsic semiconductors arranged such that current can flow in only one direction.

    Therefore, the difference is that the extrinsic semiconductor can allow current flow in both directions while the P-N junction diode permits only a unidirectional flow of current.
