An audio frequency transformer is a transformer designed to operate in the range of frequencies audible to the average human. This range is generally accepted to be from 20 Hz to 20,000 Hz. The usual purpose of an audio transformer is to match impedances between circuit sections. For example: between a microphone and the input of an amplifier, (input transformer), or between the output of an amplifier and the loud speaker. (output transformer).

Can dc current work on transformer?
Transformer is by definition can transform only AC current. But it's possible to build device that can step up or step down DC voltage directly. These are called DC-DC converters not transformers.
What difference's between potential transformer and voltage transformer?
Both are same. This is an instrument transformer used for metering & protections.
What is the definition of a core in electrical equipment?
A core in the electrical trade usually refers to the iron laminations that coils of wire are wrapped around. The core directs the magnetic field, that the coils of wire produce when energized, into a working force. This could be the iron core of a relay or a transformer core that is the centre and principle reason that a transformer can operate.
What is the name of the transformer that reduces the voltage?
a step down transformer is used to lower the voltage from the powerlines into your home. a common slang term for this type of transformer is a pole pig.
Can you use a transformer to convert modified sine wave to pure sine wave?
we cannot use transformer because transformer cannot change frequency . . .
How does an earth leakage transformer work?
What is the definition of earthing and how it works?
What is the definition of inter connecting transformer?
It is a step up or step down for power delivery.
Definition of transformer?
An apparatus for reducing or increasing the voltage of an alternating current.A person or thing that transforms something.
How do you calculate the current of the secondary side of the transformer without a load are impedance known?
Without a load the secondary current is zero, by definition.
What is the definition of an industrial transformer?
A transformer is a transformer, for the most part. The use of "industrial" here may just mean the transformer in question is constructed a little more robustly than a "regular" transformer. One generalization about transformers is that they are generally built pretty tough 'cause they are usually a bit more expensive to construct than most basic components and the manufacturer doesn't want it to fail. But the "industrial" version may be even tougher to withstand more punishment because of the application.
What is a half transformer and a half transformer?
a hole transformer
Why induction transformer called rotating transformer?
Transformer has windings
Can you use ordinary transformer in place of auto transformer?
yes we can place auto transformer in place of original transformer
What happens when load is given to primary side of a transformer?
The Load will consume part of the power and therefore reduce the current (voltage ) available for the secondary part of the transformerAnswerYou cannot apply a load to the primary of a transformer which, by definition, is the winding connected to the supply voltage. Your question makes no sense.
What is the function of fans in transformer?
The function of fans in a transformer is to regulate the transformer's temperature.
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
Can dc current work on transformer?
Transformer is by definition can transform only AC current. But it's possible to build device that can step up or step down DC voltage directly. These are called DC-DC converters not transformers.
