What do transformer coil have to do with the way the transformer control voltage in alternating current?

Transformer coils are normally used to step down power from high power lines to a power you can actually use in your house. This works through the ratio of windings on a coil to the windings on the output side.

How does a welding transformer work?
A welding transformer uses the alternating current supplied to the welding shop at a high voltage to produce the low voltage welding power
4 What is the difference between a transformer and a rectifier Which are found in a PC power supply?
A rectifier is a device that converts alternating current to direct current. A transformer is a device that changes the ratio fo current to voltage. A rectifier is found in a PC power supply.
Why is alternating current used for domestic purposes?
Alternating current is easier to distribute than direct current, because alternating current can be raised or lowered in voltage by a transformer. This allows very high voltages to be used in long distance transfer of electricity, which is then stepped down several times before being supplied to the end user. As the voltage is increased in a circuit, the current, as measured in amperes, decreases for a given load. This allows the use of lighter wire to transmit large amounts of electricity.
The incoming voltage from the current source to the transformer is called the voltag?
primary
What can't we use step-up transformer to increase the voltage by producing electricity of lower voltage?
This question is not understandable. You can use a step up transformer to increase voltage; you can't increase voltage by producing electricity at a lower voltage; this will result in current flow into your generator, not current flow out (similar to operating a generator in the leading mode). Please explain further under "discuss question".
A transformer can only the voltage of an alternating current?
A transformer can only increase or decrease the voltage of an alternating current, and it is called step-up transformer or step-down transformer accordingly.
A devise that increases or decreases the voltage of alternating current?
TRANSFORMER
What is a device used to change voltage of an alternating current?
A transformer.
What is an apparatus for reducing or increasing the voltage of an alternating current?
A transformer
Why does a transformer require alternating current?
In order to induce voltage as an output, a changing magnetic field is needed. To create a changing magnetic field in the transformer a changing current and that is an alternating current.
What type of voltage must be passed across a transformer?
A transformer must be connected to an alternating current (AC) supply of the correct voltage.
Is a device that changes the voltage of an alternating current with little loss of energy?
The device you are referring to is called a transformer. Not only can a transformer increase voltage, it can decrease voltage as well. These are known as a step up transformer for increasing voltages and step down for decreasing voltages.
A device that increase the voltage of an alternating current is called a?
That's called a transformer.
A device that increases the voltage of an alternating current is called?
That's called a transformer.
Would you expect to find an alternating or direct current in the secondary coil of a transformer?
An Alternating Voltage is induced in the secondary winding. When connected to an external load, you will have an alternating current.
Why do electric company generators produce alternating current?
Because alternating current can be run through a transformer to step up or down the voltage. High voltage current incurs lower losses in transmission.
Does a transformer rectify the alternating current?
No, a transformer changes the ac to a voltage that the user requires. After that a rectifier can be connected to it to provide dc.
