Want this question answered?
The Banded end of diode represents Cathode.If you want the diode to be forward biased then the Cathode is made more negative than Anode.For reverse biasing of Diode (Zener Diode) The Cathode is kept positive.However the mail carrier of current in the Cathode is Electrons which are negative.
Inside the diode valve the conventional curret flow is from anode to cathode. The electron flow is from cathode to anode.
The cathode of a diode is usually indicated with a band. In the absence of the band, consult the datasheet. Alternatively, use an ohmmeter that generates more than 0.7 volts at low current (a diode checker) and check conductance. The diode will conduct when the anode is more positive than the cathode.
With a 10mA forward bias current, if the voltages at the anode and cathode of a diode in a circuit are found to be the same, then the diode most likely to be shorted.
Cathode and an anodeThey are called the "anode" and the "cathode", just like every other diode ever built.

anode positive potential cathode negative potential
The cathode and anode are simply two terminals of a semi-conductor junction. In a normal diode, forward bias occurs when the anode is more positive than the cathode.
Inside the diode valve the conventional curret flow is from anode to cathode. The electron flow is from cathode to anode.
if a diode has color band markings they are on the cathode end
The two leads on a diode are called the anode and the cathode.
a diode will conduct when anode is more positive than the cathode

two, cathode & anode
With a 10mA forward bias current, if the voltages at the anode and cathode of a diode in a circuit are found to be the same, then the diode most likely to be shorted.
The end marked with a band is the cathode.
diode:= di+ iode di means two,and iode means terminal,,,, diode is two terminal device i.e anode and cathode
