Ideal transformer is useful in understanding the practical transformer..i does't have losses...
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.
Resistance ideal transformer is the one having no core losses, infinite permeability no mmf needed to set up flux), windings are having no resistances or reactances.
The properties of an 'ideal' transformer are (1) voltage ratio equals turns ration, (2) no losses.
The voltage ratio is the same as the turns ratio for an ideal transformer, and most transformers are close to being ideal. So use the following equation:Vs/Vp = Ns/Np
It doesn't really matter which way around you use a transformer, the primary winding is ALWAYS whichever winding you connect to the supply, and the secondary winding is ALWAYS whichever winding you connect to the load. For either connection, the turns ratio will ALWAYS equal the voltage ratio for an ideal transformer (or close enough for a real transformer).
ideal transformer is that which has no power losses.if any transformer transfer power to secondary without power loss then that call a ideal transformer

For an ideal transformer, the voltage ratio is the same as its turns ratio.

A transformer can never be an ideal device to transfer power. Its inherent design has limitations caused by losses WITHIN the device itself.

The properties of an 'ideal' transformer are (1) voltage ratio equals turns ration, (2) no losses.
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.
No. A transformer doesn't source or sink energy, or convert energy from one form to another.The ideal transformer merely changes the parameters of an electrical current, with no effect on energy levels.A non-ideal (real-life) transformer decreases the energy in the electrical circuit, because its lossesrob some of the energy and turn it to heat.
