What are semiconductor diode laser describe with energy band diagram the construction and working of a semiconductor diode laser?
construction and working of semiconductor laser
What is power diode generally made from?
As that of most power devices power diode are maid from silicon material(because of its wide band gap) . but now days alloy of silicon are used like sic(silicon carbide) by ank
How can you reduce back current while using relay?
You put a diode in parallel with the coil. The cathode end of the diode connects to the plus side of the coil and the anode connects to the negative side. The cathode is usually marked with a line at one end of the component.
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.
How is zener diode different from a conventional diode or ideal diode?
zener diode :zener diode operates under reverse bias voltageideal diode :ideal diode operates under forward bias voltage
How do you know which way a diode will let current flow?
Most diodes have a band (or marking), at one end. The band end is considered the positive end. You can also consider the "band" as a symbol of a gate or blockage. Power flowing from the non-band end to the band end will flow, but power flowing from the band end backwards will not. (That's my method that works for me).
How do you identify diode terminal?
The end marked with a band is the cathode.
What does the silver band on a car electrical diode mean?
The silver band shows which end is the negative (Cathode) end. If you are using it as a blocking diode, the other end (+ve Anode) should be connected to the +ve supply. Power will pass through and be available at the end with the stripe. If you put it the other way around, it will block the current.
When does the diode not allowed to flow the current?
A diode is a one-way gate for electrical current to flow through. You must have the right size diode for the amount of current that will be used in your circuit. The stripe on the diode is your output end. That is, the current must enter your diode at the non-stripe end and leave at the end with the stripe. This coincides with the diode symbol used on your schematic. If your diode is in backwards, the circuit will not work as the gate in the diode will block the current just the way it should.
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.
Which marking does not occur on a horses face?
Coronet band
What is the working principle of Light Emitting Diode and their commercial types?

What is a marking gauge used for?
A marking gauge is used for marking a bit of wood by using the screw at the end.
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.
How to study the Band gap of a p-n junction diode?
Try googling it.
What is the purpose of the coronet band?
There is no purpose to a coronet band. It is a marking on a horses leg on the very bottom by the fetlock. It is just another marking on a horse just like a star, blaze, face mask, sock, or stocking.
