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.

The terminals of a diode are called the?
anode positive potential cathode negative potential
What are the two leads on a diode called?
The two leads on a diode are called the anode and the cathode.
Which side of diode is anode and which is cathode on the diode in a schematic?
The anode is the arrow shaped end, while the cathode is the bar shaped end. You can remember this by recalling that current flows from anode to cathode in an ordinary diode; well, that is, if you use the trick of assuming that current is hole flow, rather than electron flow, a useful and common convention. The exception, of course, is the zener diode, where current flows in both directions, but at different potentials. In this case, there are two 45 degree angled bars at the end of the cathode symbol, and the normal configuration of current flow is cathode to anode, backwards with respect to an ordinary diode.
If the cathode voltage of a forward biased silicon diode is 4.5 v what is the anode voltage?
The nominal forward bias voltage of a silicon diode is 0.7V, depending on current and temperature. If the cathode is 4.5V, the anode should be around 5.2V.
Why diode is called diode?
diode:= di+ iode di means two,and iode means terminal,,,, diode is two terminal device i.e anode and cathode
The terminals of a diode are called the?
anode positive potential cathode negative potential
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 many terminals does a diode have?
two, cathode & anode
What are the two leads on a diode called?
The two leads on a diode are called the anode and the cathode.
A diode conducts only when it is?
a diode will conduct when anode is more positive than the cathode
What does diode do?
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.
A diode does what?
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.
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.
What doed a diode do?
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.
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.
Why is the negative peak of the carrier wave discarded by a diode in demodulation?
It's caused by the action of the diode. A diode conducts when its anode is positive to its cathode, or... when its cathode is negative to its anode. The above statements are saying the same thing. You circuit is applying the carrier wave to the anode, and taking output from the cathode. The diode will conduct and pass the positive peaks of the carrier from its anode to its cathode and through to the load (next component/s after the diode), but diode action will not permit conduction any time when the carrrier wave swings into negative voltage on the anode. You *could* turn the dioe around - then you would get only the *negative* peaks of the carrier wave passing through to the load.
