Why are transformers used for transmission of electricity into your home?

The voltage provided by power company are higher what your home uses so Transformers step down the voltage for your house. Higher voltages in your home would cause a potential safety hazard. The higher voltages on transmission lines are used to cope with voltage drops over long distances.

Why is ac electricity transformed?
'Transform' means to increase or to decrease an a.c. voltage. Transformers are used to step up lower voltages to higher voltages, or vice-versa. Transformers are an essential component of electricity transmission and distribution systems, as they allow voltage levels to be changed very efficiently. For a given load, the higher the supply voltage, the lower the resulting load current. So very high voltages are necessary in transmission systems in order to transfer energy with relatively-low values of current -this leads to less voltage drops along the line, less energy losses, etc. Transformers are required to increase voltages for transmission at generating stations, and to reduce voltages for the users at the far end of the transmission/distribution lines. A.C. is actually less-efficient than d.c. for long transmission lines, but is more widely used because it is very complicated to transform d.c. voltage levels, because transformers do not work with d.c.
What is wind power used for?
wind power is used for electricity in a home also it is used for hest
What kind of solutions don't conduct electricity?
One solution that will not conduct electricity is pure water. The reason is that it needs a dissociated ionic compound that can mix with water when detached, and then it will be unable to conduct.
What does aluminum foil do to electricity?
Aluminum is a good conductor of electricity. While it won't actively "do" anything to electricity, it will pass electric current if it used as part of a circuit. Aluminum is used in overhead power transmission lines as it is lighter than an equivalent copper conductor.
What are the metal pots on posts along side the roads Electric Transformers?
They are transformers. Transformers are necessary to reduce the high voltage on the lines that run along the road to a smaller voltage that can be used at a home. The power companies generate much higher voltages than those found in your home so that they can be transmitted along much greater distances.
Distribution transformer vs power transformer?
Power transformers are step-up or step-down transformers used in the electricity transmission system, whereas distribution transformers are step-down transformers used in the electricity distribution system.
How electricity energy is transferred to home and industry?
your electricity supply at home reaches you through the Nation Grid.This is a network of cables connecting power stations to homes and other buildings. The network also contains trasformers. Step-up transformers are used at power stations and Step-down transformers are used at sub-stations rear homes.
The process of transmission of the electricity generated?
Conduction. For the industrial transmission of electricity, the word "transmission" is used.
How Transformer reduce the power transmission cost?
Energy transmission is not possible without transformers. Therefore, transformers are an integral part of the transmission system. High voltages achieved using transformers result in lower currents which, in turn, allow conductors of smaller cross-sectional area to be used with transmission lines. In this sense, transformers might be thought of as 'reducing the cost of energy transmission', but as its impossible to transmit energy without transformers this is of academic interest only.
What is the definicion of power transformer?
In the electricity supply industry, the term, power transformer, is used to describe transformers that are used in the electricity transmission system (i.e. for the UK, at 400/275/132/33-kV levels), as opposed to distribution transformers that are used in the electricity distribution systems (i.e. for the UK, at 11 kV/400-230 V levels). They vary tremendously in physical size, according to their operating voltages and power ratings -typically expressed in megavolt amperes.
Electrical Properties of Transformers why you use it?
Transformers are used to convert electricity from high voltage to low voltage and from low voltage to high voltage.
What is the benefit of electrical transformer?
It is used to transform the power. It is dived into two types...Step UPStep DOwnand again it is classifed into 2 based on voltage to transform or current.AnswerThe benefit is straightforward. Without transformers, electricity transmission and distribution would be impossible. For the transmission of electrical energy, very large voltages are required, and the only efficient and economic way of doing this is with transformers.
Why are transformers used to increase the voltage before transmission?
Using a higher voltage reduces power losses during transmission.
Is petroleum product a good conductor of electricity?
No, that's why it was used in (old) transformers to cool the windings.

Why ocean water is not used to produce electricity?
I think it can be with various water turbines and water current transformers.
How are step-up and step-down transformers used in the transmission of electric current from the electric company to homes?
(This is what my teacher said, I wrote this down in my notes) The answer is, Step-up transformers are used to increase the voltage of an electric current before it is sent out over transmission lines from the electric company. Step-down transformers are used to reduce the voltage of current from high-voltage transmission lines before it enters homes and businesses. Some devices, such as televisions, contain step-up transformers that increase the voltage once again.
