What happens to the current if the potential difference is stepped-up in an ideal transformer?

In an ideal transformer, if the voltage is stepped up by a factor of x, then the current is stepped down by a factor of x. The end result is that the power, P=VI, is not changed. Again, this is in the ideal case.

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 is the full form of CT PT transformer?
CT=========current transformer PT=========potential transformer these are the instrumental transformers.
What is the difference between a transformer and a rectifer?
A transformer is used to change the value of a voltage applied to the transformer's primary winding to a different voltage value taken from the transformers secondary winding. A rectifier is used to change an alternating current value to a direct current value.
Is ct step up or step down?
'CT' is used to designate current transformers, and 'PT' is used to designate potential transformers. A current transformer provides a ratio of primary current to the secondary. A potential transformer provides a ratio of primary voltage to the secondary. A power transformer (step up or step down) resembles a PT more than a CT.
What are the precautions using current transformer and potential transformer?
Secondry of CT should never kept open during functioning
Is current produced with out potential difference?
No.
What are potential transformer?
potential transformer is that which transforms one range of voltage (potential difference ) to another range without changing frequency.AnswerA 'potential transformer' is the North American term for what, elsewhere, is called a 'voltage transformer'. It, together with a current transformer, belongs to a class of transformers known as 'instrument transformers'.Potential transformers are used to (1) reduce the value of a high-voltage supply to a lower value (often 120 V) so that it may be read by ordinary voltmeters, and (2) to electrically-isolate the voltmeter from the high-voltage source for the purpose of safety.In electricity substations, potential transformers are also used to provide an input to certain types of protective relay.
What is a transformer and its functions?
Voltage transformer or potential Transformers are used in conjunction with Current transformers for metering and protection purpose in HT and LT power system.
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).
Current is proportional to the potential difference and inversely proportional to its?
Current is proportional to the potential difference and inversely proportional to resistance. Ohm's law: Current equals voltage divided by resistance
What is the differences between current and potential transformer?
Current Transformer- Instrument transformer used for measure high current. it hasless and thin turns in primary and more and thick turns in secondary.Potential transformer- Instrument transformer used for measure high voltage. it has more and thin turns in primary and less and thick turns in secondary.CommentUnfortunately, the original answer has got things the wrong way around for the CT! A current transformer's primary has a thicker conductor than its secondary.
The difference between charge and current?
Charge is potential, current is flowing.
