What is auto transformer stater?
I think you are confusing your terms. The term 'stator' (not 'stater') is used to describe the stationary part of a rotating machine (motor, generator), as opposed to the term 'rotor' which describes the rotating part. No part of an autotransformer is normally described as a 'stator'. An autotransformer has a laminated silicon-steel 'core', around which are placed 'windings'.
Which is the maximum efficiency machine between Alternator and Transformer?
the efficiency of transformer is more than alternator, because 1- the alternator have friction and windage loss but in transformer this not occure. 2- in the alternator the flux leak is more than the transformer, because in case of alternator the flux move through the air which is dimagnet and in transformer flux move through silicon steel. 3- in the other hand alternator have dc compound generator for exciation (depend on other electric course 220volt) but in t/f is not need.
What is CRGO?
Cold-Rolled Grain Oriented silicon steel. Used in transformer core laminations. whatisCRNO? in transformers
How silicon content affect microstucture and consequently mechanical propertise of cast iron?
because the cast iron is a ferrous metal
What is function of breather and explosion vent of 3 phase transformer?
breather to observed moisture from the tank and explosion vent will works when the moisture will get observed in the tank then it will explodes from the explosion vent by breaking diaphgramAnswerThe breather allows air to enter and leave the transformer's sealed tank as the transformer oil contracts or expands. The breather is fitted with a silicon-gel chamber to ensure that any air entering the tank is dry. A viewing portal allows the viewer to determine whether the silicon gel crystals are still active.The explosion vent is a large-diameter tube, usually located at the top of the transformer tank, sealed with a frangible plate or diaphragm. Should an explosion occur within the transformer due, for example, to a catastrophic short-circuit fault, then the blast of the explosion will be allowed to escape through the explosion vent, rather than causing the transformer's tank to explode.
Why rotating electrical machines have low silicon content?
may be cost gets high

What are the internal parts of a dry electric transformer?
Insulated primary and secondary windings and a silicon-steel core.
What is CRGO?
Cold-Rolled Grain Oriented silicon steel. Used in transformer core laminations. whatisCRNO? in transformers
Is it possible for a pure quartz crystal to store data without being part of machine or without doping?
Yes, because it's part of the silicon family. It's silicon dioxide. I'm still figuring out if you need a machine or not
Why silicon gel used in transformer?
A transformer is fitted with a 'breather' pipe, which allows the air within the transformer (or its conservator tank) to enter or leave, as the oil (coolant) level changes due to contraction or expansion. As the air inside the transformer tank (or conservator tank) must be kept dry, the breather pipe is fitted with a chamber containing silica gel crystals which dry any air drawn into the transformer.
Can you tell what grade of silicon steel is in a transformer core Is it stamped somewhere?
No, the grade or alloy is not usually marked. The manufacturer's data may indicate it though.
Can silicon be mined in its pure form directly from earth?
Although silicon forms roughly 25% of the earths crust, it is rarely found as a pure mineral (Si) in nature and so is not mined as such. I believe the primary source of silicon which is mined comes from high quartz content sands. Quartz of course being composed of silicon and oxygen, (silicon dioxide).
If you were to get a plate then scratch it with an obsidian what color is the streak that is left?
Probably white because of the high silicon dioxide content.
How silicon content affect microstucture and consequently mechanical propertise of cast iron?
because the cast iron is a ferrous metal
If you have a transformer with 25.2V center-tapped secondary with two 1N4002 silicon diodes in a full-wave rectifier What is the peak value of the dc pulses?
a: 25.2 x 1.41 with no load
