How the voltage is induced in a single phase transformer?
The changing magnetic flux in the iron core of the transformer induces a voltage in the windings.
What is air gap in case of transformer?
An air gap in a transformer refers to the intentional separation between the magnetic core and the windings, or between different parts of the core itself. This gap is used to reduce magnetic losses, control magnetic flux, and improve the transformer's performance under varying load conditions. It can also help prevent saturation of the core material, thereby enhancing efficiency and stability in operation. The size of the air gap is carefully designed to optimize the transformer's characteristics.
What is the meaning of magnetic balance test?
Magnetic balance test is performed on transformer to check, whether the core and windings of the transformer is balance position or not. Magnetic Balance is a test of Critical use as it helps us to enhance the efficiency and life of transformers.
What Is a core-core type transformer?
A 'core type' transformer core is one in which the primary windings and secondary windings are placed around each of the limbs, as opposed to a 'shell type' core, in which the two windings are placed across the centre core. A core-type core is a magnetic circuit equivalent to an electric series circuit, whereas a shell-type core is equivalent to an electric parallel circuit. This is better answered with a diagram, so I suggest that you do a search on the internet.
What are the essential parts of a transformer?
A magnetic core made of iron laminations, forming a closed loop, and two or more coils of copper wire wound to intersect the core.
Is a wooden core magnetic?

Can a wooden core change an electromagnet?
Yes, a wooden core would not affect the magnetic properties of an electromagnet since wood is not a magnetic material. For maximum magnetic strength, it is recommended to use magnetic materials such as iron or steel as the core of an electromagnet.
Why in transformer core is necessary?
A transformer core is a low-reluctance magnetic circuit, which ensures that most of the magnetic flux generated by the primary winding links with the secondary winding. Without a core, little of the magnetic flux generated by the primary winding will link with the secondary winding.
What is the function of the core?
the function of core is to provide path to magnetic flux,a core may be armature core or may be transformer core
Why do you get a typical sound when the transformer is put into operation?
vibration of the transformer's laminated core in response to the AC magnetic field.

Why core losses are always fixed in transformer?
Core losses are losses in the magnetic system of the transformer, such as eddy currents in the core, hysteresis losses, etc. Because of this, the losses are constant, regardless of load, assuming voltage and frequency stay fixed.
Why the output voltage from a transformer is zero if a direct current flows through the primary coil?
A transformer relies on AC current flowing through the primary to set up changing magnetic fields in the core. The field flows through the core and in to the secondary of the transformer, generating an AC current. The current must be AC, otherwise the magnetic field in the core of the transformer will saturate. In the same way, the armature of a dynamo or alternator must be moving in order to create a changing magnetic field to create current through the windings.
What is the difference between core type and shell type transformers?
The difference is between how the windings relate to magnetic material around which they are wound. If this magnetic material surrounds the windings then the device is said to be a shell type transformer. If the windings cover the exterior of the magnetic material then the transformer is said to be of the core type. Please see the link.
