the most basic Transformers have at least two coils, a primary and a secondary. A transformers nameplate will provide you with the max allowed voltage and current, as well as a voltage per turn ratio. for example a step down transformer could have a primary of 120 volts and a secondary of 24 volts this would give you a ratio of 5:1.
What else can I help you with?
What type of transformers are used to step down a voltage for general use and what type of systems are they classified as?
The transformer you describe is being used as a step-down transformer, and is classified as an electrical machine. The transformer could either be a mutual transformer, consisting of two, electrically-isolated coils, or an auto-transformer which uses a common coil between its primary and secondary circuits.
What are the two coils in a transformer?
primary and secondary coilsAnswerPrimary and secondary windings.
What will be the voltage 10 coils on the primary side with an input of 120 volts and 2 coils on the secondary side?
In order to determine the output voltage of a transformer, you need to specify the turns ratio between primary and secondary. You did not do that, nor did you provide any other information that could be used to deduce the output, so only a general answer can be given. The output voltage of each secondary is 10 volts (the input voltage) times the number of turns on the primary divided by the number of turns on the secondary. If, for instance, the ratio was 1:3, then the output would be 30 volts. Since there are two secondary windings, this calculation is performed independently for each secondary.
What must be the rms voltage rating of the transformer secondary for the voltage doubler that produces an output of 500 v?
The transformer should provide 144-0-144 v to have a no-load voltage of 500 v dc in a voltage-doubler using two diodes.
What does the inside of a 3 phase transformer look like?
A three phase transformer has three primary coils and three secondary coils wound on a laminated iron core shaped like the capital letter 'E'. Each pair of primary and secondary coils are wound concentrically onto each leg of the 'E'. There is a straight , laminated core segment, that connects across all three legs of the 'E', forming a circuit path for the magnetic flux. The primary and secondary coils can be arranged as an autotransformer, with the primary and secondary coils connected end-to-end, with a common conductor tapped at the interconnection, or as separate coils with two separate connections for each coil.
What is an electrical device that changes the voltage of electricity through the use of two sets of coils.?
The electrical device is a transformer.

The electrical device is a transformer.
Which device consists of two separate coils of wire wrapped around an iron ring?
A transformer consists of two separate coils of wire wrapped around an iron ring. The primary coil induces a changing magnetic field in the iron core, which in turn induces a voltage in the secondary coil. This allows for the transfer of electrical energy between the two coils.
Why ac current is used in a transformer?
AC current or DC current can be used in transformers. A transformer is made of two coils of wire, the input coil induces a current into the output coil. Transformers change the voltage either up (step up transformer) or down (step down transformer). The amount of change in voltage is dependent solely on the number of windings in both coils in the transformer. DC transformers work exactly the same way AC transformers do.
What is an instrument transformer?
An 'instrument transformer' is a category of transformer used to supply measuring instruments or protective relays. There are two types of instrument transformer: a 'voltage transformer' (known as 'potential transformer' in North America), and a 'current transformer'. They are used with high-voltage systems, where it is hazardous to connect instruments directly to such systems.Voltage tranformers are used to reduce high-voltages down to a level that can be safely applied to voltmeters, or to the voltage-coils of wattmeters or energy meters, or to protective relays, while electrically-isolating those instruments (and personnel) from the high-voltage supply.Current tranformersare used to reduce high-voltage currents down to a level that can be safely applied to ammeters, or to the current-coils of wattmeters or energy meters, or to protective relays, while electrically-isolating those instrument (and personnel) from the high-voltage supply.
What is the difference between transformers and adapters?
A transformer is a component that changes AC current from one voltage to another. A transformer consists of two coils, one connected to the input, and one connected to the output. A transformer can convert voltage up or down, depending on the number of windings on the coil. An adapter MAY include a transformer to change the voltage, but an adapter usually changes the voltage AND converts from AC to DC as well, and may have a regulator that locks the voltage to prevent a surge and other components that prevent what is called "ripple".
What type of a device is used to increase or decrease the voltage in an electric circuit?
A transformer. A small example is the coil in a motorcar. A transformer, in a power line, only changes voltage in one direction under normal usage. At distribution voltages, about 8360 VAC, the voltage is monitored by a regulator. A regulator either increases or decreases the voltage automatically to insure the desired voltage is steady. This regulated voltage is then fed to transformers to provide customers with a regulated voltage at the desired voltage.
How does step down transfomers work?
A transformer has two coils of wire wound round an iron core. An ac voltage on one coil produces a magnetic field in the core. The magnetic field causes a voltage to be induced in the second coil. A step-down transformer has fewer wire turns in the second coil, therefore the output voltage is less than the input voltage.
Why transformer is called static device?
A transformer has two coils wound over a core. Depending on use, the two coils are named primary and secondary coils. The primary and secondary coils are linked magnetically (not electrically except in case of auto transformers) called mutual coupling. When the primary coil is excited with alternating voltage(A.C), varying magnetic flux is produced which links with the secondary coil and thus a voltage is induced in the secondary coil. Since there is no rotating or moving part utilized for the above process hence transformer is called a static device. The word static used here should not be confused for static charges. It only signifies "not moving"
What are the basic construction of a single phase transformer?
two coils and a metal plates

What is the prinicple of apower transformer?
An electrical transformer consists of a two sets of coils, called a primary winding, and a secondary winding. These are electrically separate from each other, and are coupled together magnetically via an iron core. (Of rather special design). It is called a transformer because it transforms one voltage (in a.c.) into another voltage.The amount of power able to be transferred between the coils is governed by the amount of iron in the core. If each winding had the same number of coils of wire, then the transformer would produce a voltage at the output equal to that at the input. This would be called an isolating transformer and are used for safety reasons.If the secondary had twice the number of turns as the primary, then the voltage produced would be twice that of the primary. But the current would still be limited by the size of the iron core, and by the size of the wire in the windings. In this example, the current available would be halved.It is common for a transformer in an electronic system to have multiple windings, some low voltage, some medium voltage, and some high voltage. And they may be used to reduce the voltage as well as to increase it.
