Both Current and Potential Transformer are instrument Transformers which are used to measure very high current and voltage respectivly.
Current Transformer is a Step up transformer and used to measure high current, its secondry is connected to ammeter of very small capacity (usally 5 A) but its Scale is calibrated according to actul values.
Potential Transformer is a step down tansformer and its secondry is connected to voltmeter of small range but again the scale is calibrated for actul values.
So as a whole both Current and Potential Transformers are used to measure high values of Current and Voltage respectivly.
A transformer can be used for two main purposes:
1. Change the input voltage to a higher or lower level.
2. Match the impedances of two devices, in Musical Instruments for example.
3. Physically isolate one source from another.
Hope that clears that up.

The main use of a transformer is to change an AC voltages from one potential to another. The AC voltage can be raised from lower potential to a higher one or from a high potential to a lower one. The voltages are determined by the ratio of turns between the primary coils to the secondary coils for each individual transformer.
can be used for stepping up n stepping down voltage/current n also as isolation of load from the power circuit.
the auto transformer is the one winding transformer. it ismaily used in practical purpose.
A single-phase transformer works with a single-phase supply, while a 3-phase transformer is used with a 3-phase supply. A single-phase transformer has 2 wires on the primary and secondary (ignoring taps) while a 3-phase tansformer has 3 or 4 wires on the primary and secondary.
A transformer is an electrical device that takes electricity of one voltage and changes it into another voltage.
A DC voltage added to one side of a transformer has no effect on the other side.
the alternating kind
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.
One of the most common uses is as a seasoning for food.

One of the most common uses for a euphemism is to advise someone of the death of a loved one.
there is alot of uses of granite but the most common one in the u.s, canada, europe,and australia are bathroom tiles hope this helped:)
You will need a standard AC transformer. You can purchase the transformer at most Home Depot's.
An auto transformer has one winding with the output being tapped at some point and therefore has no isolation between primary and secondary. This may make it unsafe or illegal in some applications. A common power transformer has separate windings.
Eating healthy is just one of the most common uses of 'healthy'
Spray bottles are used for spraying fluids.There is not one most common use for them. But some of the popular ones are spraying water,cosmetics and chemical fluids.
One of the uses of coal is for power.
