How does X0 work in case of ideal transformer, because R0=0 means short circuit.
In practical inductive reactance always exists with resistance...it means Z=R+jX....R and X can not be zero....R0 and X0 ..in transformer is magnetising parameters...you can go for equallent circuit transformer expression...
Practical inductive reactance has R and X but R0 and X0 be assumed in a transformer.
To get the work as transformer (to enerzised), magnetization of core is must.It is a pure inductive circuit only inductive reactance (Xo) would have been considered, but in practice, no core is ideal, and is having loss component(Ro=stamping resistance), hence to get voltage on secondary side,the no load current have two component magnetizing current(V/Xo) is component , lag 90 degree, and ,another in phase (loss or eddy current) component(V/Ro). Total no load current is vector addition of two currents, hence Ro and Xo are always in parallel to applied voltage.
