A thin film of aluminium oxide forms when aluminium is exposed to air. This layer protects the rest of the aluminium from corrosion.
Aluminium is much less reactive than Lithium.
by using electrolysis
Aluminium borate does not have a valency. borate and aluminium have different valencies as aluminium and borate are separate elements. aluminium's valency is +3 and borates is -3
Aluminium foil is made from pure aluminium; aluminium sulfide is Al2S3.
In a transformer it is known as the transformer core.
They have both.
This isn't the case. You can have aluminium or copper on primary or secondary side of a transformer.
mylif eis here
there will be no neutral point in the circuit and high voltage will be across the transformer coils
The electrical device is a transformer.
Due to the heavy coils found inside the body also you will find an insulation that is oil type, that s why it s so heavy , but if u look at the dry type transformer u will find it so light and compact that s all i know my sir Eng: Amr <<>> The reason that power transformers are so heavy is from the steel laminations that the core of the transformer is built from. The outside transformer is constructed out of steel which also adds to the weight. Transformer coils these days are using aluminium wire for the primary and secondary wraps. This keeps the weight down and also helps in preventing copper theft.
The more coils you have on one side will increase the magnetic force
two coils and a metal plates
I think you mean 'turns' rather than 'coils' (a coil is made up of a number of turns). The answer is that, yes, the turns ratio is the same as the voltage ratio, for an ideal transformer.
A transformer is fundamentally a set of coils; therefore, a transformer is an inductive load. However, by "transformer load", you seem to mean "the load that is connected to a transformer". Whether that load is inductive or capacitive depends mostly on what is hooked up to the transformer.
