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.
A diode is a semiconductor meaning it will conduct from anode to cathode if the anode is held positive. Reversing the polarity Will in effect block current flow.
Inside the diode valve the conventional curret flow is from anode to cathode. The electron flow is from cathode to 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 Anode. Think of the arrow like a Capital Letter A standing for the Anode.
If it's new, the cathode is the shorter lead.There may be a flat on the round base (on round ones) = cathodeThe larger electrode inside is the cathode.
Connect the positive lead of the tester to the anode of the diode and the negative lead to the cathode. If the tester displays a voltage drop or a forward bias reading, the diode is forward biased and the anode is positive. If the tester displays an OL or reverse bias reading, the diode is reverse biased and the anode is negative.

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.
The two leads on a diode are called the anode and the cathode.
