As we know that rate of change of flux linkage depends on secondary winding so ideally almost all of the flux of primary and secondary winding should link to secondary that means it is very much important that the inductive coils should be connected to each other to become an ideal transformer.

A transformer is an electrical device that is used to transfer electrical energy between two or more circuits through electromagnetic induction. It consists of two or more inductive coils, known as windings, that are electrically isolated from each other but magnetically linked by a common magnetic core. The primary winding is connected to the input voltage source, while the secondary winding is connected to the load.
The ideal transformer is a theoretical concept that assumes certain idealized conditions are met. These ideal conditions include:
1. Ideal magnetic core: The magnetic core of the transformer has infinite permeability and zero magnetic losses. This means that the magnetic field produced by the primary winding is perfectly coupled to the secondary winding without any energy losses.
2. No resistance or leakage inductance: The windings have zero resistance, meaning that there are no losses due to electrical resistance. Additionally, there is no leakage inductance, which means that all the magnetic flux generated by the primary winding is perfectly linked to the secondary winding.
3. Conservation of energy: The power input to the primary winding is equal to the power output from the secondary winding, assuming no losses. This means that the transformer operates at 100% efficiency.
Based on these ideal conditions, the equivalent of an ideal transformer is when inductive coils are connected in both the primary and secondary circuits. This is represented by option 'D' in the given choices.
Explanation:
- Inductive coil connected in the primary circuit: The primary coil is responsible for receiving the electrical energy from the input voltage source. When an alternating current flows through the primary coil, it generates a magnetic field that is coupled to the secondary coil.
- Inductive coil connected in the secondary circuit: The secondary coil is responsible for transferring the electrical energy to the load. The magnetic field generated by the primary coil induces an electromotive force (emf) in the secondary coil, which causes a current to flow through the load.
By connecting inductive coils in both the primary and secondary circuits, the ideal transformer ensures that the magnetic field generated by the primary coil is perfectly coupled to the secondary coil, resulting in efficient energy transfer between the two circuits.
In summary, an ideal transformer is equivalent to having inductive coils connected in both the primary and secondary circuits. This configuration allows for efficient energy transfer between the two circuits, assuming idealized conditions are met.
