Yes, diodes are very polarity sensitive. They conduct in one direction, the forward bias state, where the anode is more positive than the cathode, and they do not conduct in the other direction, the reverse bias state, where the cathode is more positive than the anode. (Assuming you do not exceed forward current or reverse voltage limits.) This is how diodes "rectify", i.e. convert from AC to DC.
This is for normal diodes. Zener diodes are different. They conduct in both directions, but at different voltages. The forward voltage is similar to a normal diode, typically around 0.6V to 1.4V, while the reverse voltage is higher, such as 5.6V, which is how a zener diode can be used in a voltage regulator circuit.
If, however, when you say "polarised", you mean the action of "polarising" an automobile's electrical system, do not even think about it. That technique is no longer necessary since the advent of the alternator. Besides, that technique involves shorting out the battery, which has always been a highly dangerous operation.
a diode is a device that alows current to flow in one direction you have power diodes which are used in rectification processes and high current operations but the two main families of diodes are solid state diodes or valve operated diodes.
diodes are commonly used for rectification
what are the different types of diodes and their appplications
Today, all diodes are semiconductor diodes. However, the first diodes were piles of washers of different metals that together made a diode, and specially constructed vacuum tubes. There may still be markets for other types of diodes in very high voltage circuits, but you or i are unlikely to come in contact with them.
Advantages of Trapatt:• higher efficiency than impatt• very low power dissipationAdvantages of Impatt:• This microwave diode has high power capability compare to other diodes.• Output is reliable compare to other diodes.

Through an atmosphere of Ozone, electromagnetic waves can become polarised.
Because LED means light-emitting diode and the clue is in the diode, because diodes are 'polarised', which means that the current must flow in the correct direction for them to operate correctly.
1. general purpose diodes 2. fast recovery diodes 3. schottky diodes
There are so many different types of diodes. Some of the common examples include light emitting diodes, silicon diodes, zener diodes and so many more.
No. Diodes are diodes. One diode can be USED as a half-wave rectifier. Four diodes can be used to build a bridge rectifier.
In China Polarised Ray ban is made of Plastic Lens. If not polarised,than be glass lens. Any way you may feel light when wearing polarised plastic lens and feel a little heavy in glass lens. But polarised is easy to be scratched. So should be careful when wearing . Hope this can help you !!
The Diodes was created in 1977.
The Diodes ended in 1982.
it is not spherical or distorted.
