Explain the working of a transformer and its components.

Question

Accepted Answer

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

Transformers work on the principle of electromagnetic induction.
They consist of two or more coils of wire, known as windings, which are wound around a core made of magnetic material.
The primary winding is connected to the input voltage source, while the secondary winding is connected to the load.
When an alternating current flows through the primary winding, it creates a changing magnetic field in the core.
This changing magnetic field induces a voltage in the secondary winding, which is then used to power the load.
Transformers can step up or step down the voltage depending on the ratio of the number of turns in the primary and secondary windings.
They are commonly used in power distribution systems to increase or decrease the voltage levels for transmission and distribution.
Transformer parts include the core, windings, insulation, and cooling system.
The core provides a path for the magnetic flux and is usually made of laminated iron or steel to reduce eddy current losses.
The windings are made of copper or aluminum wire and carry the electrical current.
Insulation is used to separate the windings and prevent short circuits.
Cooling systems such as fans or oil-filled tanks are used to dissipate heat generated during operation.

Max control the voltage drops in high voltage

Accepted Answer

The core of the transformer works to direct the path of the magnetic field between the primary and secondary coils to prevent wasted energy. Once the magnetic field reaches the secondary coil, it forces the electrons within it to move, creating an electric current via electromotive force
