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
