Q1. What is transformer?
Ans. 
A transformer is a static electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
• Consists of two or more coils of insulated wire wound around a core

• Primary coil receives electrical energy and induces a magnetic field in the core

• Secondary coil receives the magnetic field and converts it back into electrical energy

• Used in power distribution, voltage regulation, a...read more

Q2. What is transformer principle?
Ans. 
Transformer principle is based on the phenomenon of electromagnetic induction, where changing magnetic field induces voltage in a coil.
• Transformers work on the principle of electromagnetic induction

• They consist of two coils, primary and secondary, linked by a magnetic core

• When alternating current flows through the primary coil, it creates a changing magnetic field

• This changing magnetic field induces a voltage in the se...read more

Q1. Transformers losses to be defined
Ans. 
Transformers losses refer to the energy lost in the transformer during the process of converting electrical energy from one voltage level to another.
• Transformers losses can be broadly classified into two categories - copper losses and iron losses.

• Copper losses occur due to the resistance of the transformer windings and are also known as I²R losses.

• Iron losses occur due to the magnetic properties of the core material an...read more
