To step up or step down a particular voltage using the principle of electromagnetic induction. This is a potential transformer.
Transformers are also used to step up or step down current. Current transformers are used extensively in instrumentation applications.
Current and voltage are inversely proportional.

Why transformer is used?
A transformer used to step up or down the value of voltage.
Difference between potential transformer and current trasnformer?
The difference between current transformer and potential transformer is that the secondary of a current transformer can not be open circuited while under service whereas that of the potential transformer an be open circuited without any damage to the transformer.
What type of transformer has only a single winding?
the auto transformer is the one winding transformer. it ismaily used in practical purpose.
What type of transformer used in bed lamps?
If the bed lamps use a low voltage bulb then the type of transformer will be a step down transformer.
How is current controlled in welding transformer?
in welding machine, the transformer used is basically a current transforrmer. so by changing the tap of secondary side of transformer, we can increase or decrease the current in the transformer.
Why transformer is used?
A transformer used to step up or down the value of voltage.
What is the transformer used in ups?
simple step up transformer
Oil filled transformer is usually used indoor or outdoor?
An oil filled transformer is usually used outdoors and a dry core transformer is usually used indoors.
What is the difference between power transformer and instrument transformer?
A power transformer is used to provide power (to your home, for example), an instrument transformer is used to measure voltage or current (for metering, for example).
What is the difference between control transformer and Potential transformer?
Control transformer used only for control supply 110,220, 24,12V AC. But Potential transformer used voltage measurement purpose.
Where is the use of earth transformer?
It is used in where the transformer are connected in star delta.
How is a transformer utilized?
Transformer is used for stepping up or down the voltage.
What difference's between potential transformer and voltage transformer?
Both are same. This is an instrument transformer used for metering & protections.
When is a step up transformer used in relationship as to when a step down transformer is used?
If the voltage needs to be increased from a lower voltage to a higher voltage a step up transformer is used. If the voltage needs to be lowered from a higher voltage to a lower voltage a step down transformer is used.
What is linear transformer?
The Linear Variable Differential Transformer is a type of electrical transformer used for measuring linear displacement. A counterpart to this device that is used for measuring rotary displacement is called a Rotary Variable Differential Transformer.
Difference between potential transformer and current trasnformer?
The difference between current transformer and potential transformer is that the secondary of a current transformer can not be open circuited while under service whereas that of the potential transformer an be open circuited without any damage to the transformer.
Can you use transformer with your 110 aircon?
A transformer can be used to change the voltage to an appliance. The voltage rating of the transformer should be right for the voltages used, and the current rating of the transformer should not be less than the current drawn by the equipment.
