Selenium rectifiers, with their metal fins and long lived application in battery chargers and in tube type television sets are not intended to be repaired. Once a rectifier plate becomes damaged or it is burnt (unmistakable stink), the entire assembly should be replaced.

What is the use of selenium photocells?
Because of its photovoltaic and photoconductive properties, selenium is used in photocopying, photocells, light meters and solar cells. Its use as a photoconductor in plain-paper copiers once was a leading application but in the 1980s, the photoconductor application declined (although it was still a large end-use) as more and more copiers switched to the use of organic photoconductors. It was once widely used in selenium rectifiers.
Who made Selenium?
Jons Jacob was the man to discover Selenium.
What are the Advantages and disadvantages of rectifiers?
There are different types of rectifiers including silicon controlled rectifiers. Advantages for this type of rectifier include that it can switch high voltages and is simple to control. Disadvantages include it cannot be turned off easily.
Is selenium a nonmetal?
Yes. selenium is a non metal
Is selenium a mixture?
No, selenium is a element
Why germanium is not suitable for rectification?
Any semiconductor can be used for rectification, so germanium is suitable.However what you may be thinking of is power rectifiers. Germanium cannot operate with a junction temperature above about 60C, so this is a significant limitation on the power handling capability of germanium power rectifiers (even copper oxide or selenium power rectifiers can handle more power, so they were used for many years before quality silicon power rectifiers became available).

The purpose of 240V to 12V rectifiers?
The purpose of rectifiers is to change AC to DC.
What are the applications of precision rectifiers?
Precision rectifiers are used in the design of instrumentation systems.
Where can rectifiers be bought for a good price?
Maplin offer affordable rectifiers. Rectifiers are used to convert alternating current to direct current. The process is also known as rectification. Rectifiers are often found serving as components of DC power supplies.
What is a polarization rectifier unit?
Chemical Processes often have large power rectifiers as their primary source of DC Power. If these rectifiers are turned off, either for maintenance or a malfunction, there is a danger to the hardware of the chemical process. To solve this problem, standby rectifiers are installed in parallel with the main rectifiers. These rectifiers, known as Polarisation Rectifiers, pass electric current through the process and prevent damage....NEOWATT ENERGY
Is fans used in rectifiers?
no
What is the purpose of rectifiers?
voltage
Why not stepup transformer is not used in rectifiers?
Rectifiers turn A/C into D/C, but transformers can only run on A/C.
Who made Selenium?
Jons Jacob was the man to discover Selenium.
What is the correct name for SeF6?
This compound is called selenium hexafluoride.
