Add your answer
Q2. What is Transformer
Ans. 
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
• Consists of two coils of wire, known as primary and secondary coils

• Primary coil receives electrical energy and creates a magnetic field

• Magnetic field induces a voltage in the secondary coil, transferring energy

• Used in power distribution, voltage regulation, and electrical isolation

• Exampl...read more

Q3. What is mutual Induction
Ans. 
Mutual induction is the process where a changing current in one coil induces a voltage in another coil.
• Mutual induction occurs when two coils are placed close to each other and the magnetic field produced by one coil induces a voltage in the other coil.

• The induced voltage in the second coil is directly proportional to the rate of change of current in the first coil.

• This phenomenon is the basis for the operation of tran...read more

Q4. What is flux, Current
Ans. 
Flux is the flow of electric or magnetic field lines through a surface, while current is the flow of electric charge.
• Flux is a measure of the flow of a physical property through a given area.

• In electromagnetism, flux refers to the flow of electric or magnetic field lines through a surface.

• Current is the flow of electric charge through a conductor.

• Flux and current are related through Faraday's law of electromagnetic ind

Q3. Describe about Pipe earthing of DTR
Ans. 
Pipe earthing of DTR involves using a metal pipe buried in the ground to provide a low-resistance path for fault currents.
• Metal pipe is buried vertically in the ground near the DTR

• The pipe is filled with alternate layers of charcoal and salt to improve conductivity

• A copper wire is connected to the pipe and then to the DTR for grounding purposes

Q2. What is rectifier
Ans. 
A rectifier is an electrical device that converts alternating current (AC) to direct current (DC).
• Rectifiers are commonly used in power supplies to convert AC voltage to DC voltage.

• They are made up of diodes, which allow current to flow in only one direction.

• Rectifiers can be half-wave or full-wave, depending on the number of diodes used.

• Examples of rectifiers include bridge rectifiers, vacuum tube rectifiers, and soli

Q4. Transformers rating in KVA
Ans. 
Transformers are rated in KVA (kilovolt-amperes) to indicate their power capacity.
• KVA stands for kilovolt-amperes, which is a unit of apparent power.

• The KVA rating of a transformer indicates the maximum amount of power it can handle.

• Transformers are available in various KVA ratings to suit different power requirements.

• Higher KVA ratings indicate higher power capacity.

• For example, a transformer with a 100 KVA rating can
