    im sure this is an easy question for most of you guys. when someone says that a transistor, diode, etc is forward or revered biased, does that mean conventional flow or electron flow? so if i have a diode ----->|----- that is forward biased does that mean "following the arrow"? ty

    A forward biased diode has a voltage at the cathode that is negative relative to the one at the anode. When conducting, the diode will have electrons come in the cathode and exit the anode. Current flow is against the arrowhead.

    The arrow on diode and in BJT transistor show conventional current flow.
    And in MOSFET arrow show electron current flow.

    In general, when something is reversed biased, it is not conducting. When it is forward biased, it is conducting.
