    Hello,
    The diode will conduct only when its cathode voltage is less than anode voltage. If you connect +5V at both the electrodes current conduction will not take place.

    Forward bias: Anode is more +ve than cathode.

    Reverse bias: Cathode is more +ve than anode.

    I hope this will clear your doubt.

    The diode is forward biased if
    diode +ve terninal to +5V battery Diode -Ve terminal to GND
    Thus forward current flows

    Diode has 2 region, One is P type and another is N type..
    current conduction take place bcoz of relative moments of their majority charge carriers.. (mean hole in P region and Electron in N region)
    now if we comect +ve teminal of +5vbattery to anode(P type) and ground(-ve terminal of battery) to cathode (n Type),then holes from Ptype moves to N type region.. and Electrons from n to P type... this relative moment of charge carrier convert in to current conduction...

    here you want to contect +5v at both side then electrons in ntype can not move towards the p type but it attract towards the cathode.. so there is no relative moment between ho;e and electron and current conduction will not take place...

    you must connect anode to more positive with respect to cathode..for current conduction..
