What else can I help you with?
Is the banded end of a diode positive or negative?
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.
What is the direction of current flow in a diode valve?
Inside the diode valve the conventional curret flow is from anode to cathode. The electron flow is from cathode to anode.
How to identify the anode and cathode of DR 25 diode?
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.
When a 10mA forward bias current and the voltages at the anode and cathode of a diode in a circuit are found to be the same what is the diode most likely to be?
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.
What is the left leg of the led called?
Cathode and an anodeThey are called the "anode" and the "cathode", just like every other diode ever built.
Is the banded end of a diode positive or negative?

The terminals of a diode are called the?
anode positive potential cathode negative potential
What is the purpose of an cathode and an anode in a diode?
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.
What is the direction of current flow in a diode valve?
Inside the diode valve the conventional curret flow is from anode to cathode. The electron flow is from cathode to anode.
A diode conducts only when it is?
a diode will conduct when anode is more positive than the cathode
What are the two leads on a diode called?
The two leads on a diode are called the anode and the cathode.
What end of a diode has the band marking?
if a diode has color band markings they are on the cathode end
What is the negative leg of an LED called?
The side of any diode that must be negative in order for the diode to conduct is the "cathode".
How to identify the anode and cathode of DR 25 diode?
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.
How many terminals does a diode have?
two, cathode & anode
When a 10mA forward bias current and the voltages at the anode and cathode of a diode in a circuit are found to be the same what is the diode most likely to be?
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.
How do you identify diode terminal?
The end marked with a band is the cathode.
