There are basically 4 major differences :-
1. The windings (both primary and secondary) of an ideal transformer are
considered to have zero resistance, hence the transformer is lossless.
2. There is no leakage flux in an ideal transformer.
3. The permiability of the core material in ideal transformer is considered to be
tending to infinity and hence the current needed to set up the flux in the
transformer is negligible.
4. There is zero hysterisis and eddy current losses in an ideal transformer.

TaigaAn ideal transformer is the one whose windings do not have any ohmic resistance and whose core does not have any leakage flux and eddy current losses.
A practical transformer is the one whose windings do have some amount of ohmic resistance and the core also have some leakage flux and eddy current losses.

What is zero voltage regulation in transformers and what it means?
'Zero voltage regulation' indicates that there is no difference between its 'no-load voltage' and its 'full-load voltage' -this is only the case for an 'ideal' transformer.
How do you calculate the transformer turns ratio?
For an ideal transformer, the voltage ratio is the same as its turns ratio.
What is the elementary theory of an ideal transformer?
A transformer can never be an ideal device to transfer power. Its inherent design has limitations caused by losses WITHIN the device itself.
What is leakage current in transformer?
In low voltage and electronics Leakage Current is any current that flows when the ideal current
What is the voltage regulation of an ideal transformer?
Ideally the voltage regulation voltage of a transformer should be zero. It means when you change the load from no load to short circuit (theoretically, normally you don't want to burn the transformer windings) the output voltage doesn't change and remains equal to the no load voltage.
