∙ 11y agoA transformer (electrical device) is used to "transform" one AC (alternating current) voltage to another.
It can also be used as an isolation mechanism to couple two signal voltages when an electrical connection between the two sides must be avoided.
When a transformer is used in a "step-up" application/configuration, the output voltage is HIGHER than the input, but its current is LOWER than that of the input.
The reverse is true when used in a "step-down" application.
When the transformer is neither step-up or step-down, it is called an ISOLATION transformer, also commonly called a 1:1 (one to one) transformer. In this case, the voltage and current of both input and output are closely similar, although the device itself costs some energy as inherent "losses". In most cases, these losses are regarded as negligible.
Transformers come in many types, configurations, and are fabricated using a variety of materials and technologies. Generally speaking, the larger physical size of the device, the greater the power handling capability.
Examples of transformer types: audio, inverter, power, signal, high-voltage (neon sign), current, variable (variac), matching, etc.
Examples of materials used (typically with copper windings): iron core, ferrite core, piezoelectric, powdered metals (alloys), etc.
A "current transformer" is specialised transformer used to measure the amount of current flowing through another conductor. This device basically consists of a ring containing a copper coil, with or without magnetic core material, through which the current-carrying wire conductor to be monitored passes. The current flow in this conductor induces a voltage that is directly proportional to the current flow. This voltage is measured to get an accurate reading of the current without requiring an electrical connection, allowing high voltages/currents to be measured safely. An everyday example of this type of device is the clamp-on current meters that use a spring-loaded split ring of metal laminations, which is opened and closed on or around a wire for measurement. (Think making an "o" with index finger and thumb) One brand is "Amp-Clamp".
A final version of transformer, although regarded as one, is actually a "choke" or "power inductor". They appear similar to a typical magnetic transformer, except that they have only one coil and only two terminations. They are basically a one-coil transformer built the same way but lacking an output coil. Acting as an "electrical spring", they are used as a ballast in AC circuits to absorb electrical energy when it's plentiful, and supply it when it isn't - operating at multiple cycles per second.

∙ 14y agoTransformers main uses is to transform electrical power into high voltage (low current) to enable economic transmission of power before transmitting electrical energy over long distances through wires.
Transformers are also used in electronic devices to step down the supply voltage to a level recommended for low voltage circuits.
A transformer is used to change a voltage potential from one value to another. Terminology; for secondary voltage higher than the primary (step up), secondary voltage lower that the primary (step down).

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
What is uses of tapped coil?
If question is about a transformer's tapped coil then the taps are a way of getting different voltages from one transformer. The end of the transformer's coil is the common point and the taps to this common point will give different voltages depending on where in the coil the taps are taken from.
Advantage of a transformer over a transformer coupled circuit?
Sounds more like a "homework" or "test" question, rather than a real-world question, and vague, at that! Could you re-phrase your question in a better, more-precise context, or check it for typos? Right now, your question seems to ask "What's the advantage of using a transformer, instead of using a transformer-coupled circuit?"...which makes no sense, since a "transformer-coupled circuit" USES a transformer.
What does filter do in a transformer?
A transformer does not use a filter. You may be asking about the use of a filter in a power supply. A power supply uses a filter to change pulsating DC from the rectifier into smooth DC for the circuits that the power supply powers.
What difference's between potential transformer and voltage transformer?
Both are same. This is an instrument transformer used for metering & protections.
What are the types of and uses for a transformer?
There are two types of transformers:- 1. Step-up transformer & 2. Step-down transformer. A transformer used to increase the voltage is called Step-up transformer. A transformer used to decrease the voltage is called Step-down transformer. Uses of step-up transformer:- in power supply stations, in picture tubes of TV, computer monitors, halogen lights, etc. Uses of step-down transformer:- in supply of electricity to homes, in the power supply to the low voltage devices like radio, music systems which are run by AC mains.
How and why is electricity transformed for different uses?
Using a transformer.
Can you sub a 240 volt 1.5 amp transformer in place of a 240 volt 3 amp transformer?
If the load you are connecting to the transformer uses 1.5 amps or less, yes.
How do you test chopper transformer?
A chopper transformer is a kind of transformer used in an switching power supply.The primary input voltage of it is a Direct current (D.C) unlike any other ordinary step down transformer which uses an Alternating Current (A.C).Chopper transformer uses a switching transistor to produce a secondary voltage..
What equipment uses Nlb200050w1a ac adapter?
Transformer Power Supply
What are possible uses of a single phase 30VA transformer?
To continuously supply a load of up to 30-V.A at the rated secondary voltage of the transformer.
Uses of transformer?
transformers are used to step up or step down the voltages
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
How many gallons of oil in a 2500 kva 12470 480 volt transformer?
Oil is used to cool the transformer. There is no telling what the transformer in question uses without knowing the specific part number and looking up the specification.
Does 110 volts cost more if uses stepdown trasformer?
If you have to pay for the stepdown transformer, yes. If that is provided free, there is a small loss of energy in the transformer, maybe about 5%, and it depends on whether the meter is installed before or after the transformer.
What is a electrical device that uses electromagnetism to change voltage from one level to another?
transformer.
What is the difference between capactive voltage transformer and potential transformer?
A capacitive voltage transformer (CVT) uses a (usually two) stacks of capacitors to reduce the votlage to a smaller internal potential transformer (PT). This makes them less expensive than an equivalent PT, but there can be a loss of accuracy.
