What is electromagnetic induction and how is it used in a transformer?
Electromagnetic induction is the process by which a changing magnetic field generates an electric current in a conductor. In a transformer, this principle is utilized by having an alternating current flow through a primary coil, which creates a varying magnetic field. This magnetic field induces a voltage in a secondary coil, allowing for the transfer of electrical energy between the two coils and enabling voltage transformation. Transformers are essential in power distribution, allowing high voltages to be stepped down for safe use in homes and businesses.
Why torque produced in case of induction motor but not produced in case of transformer?
significant tortion stresses are present in a transformer as well. They're put together with the intent of not having parts move, as opposed to a generator, where certain parts are expected to move.aage apni maa se pata kar ..
What is an ideal transformer Draw the no load phasor diagram of transformer?
Resistance ideal transformer is the one having no core losses, infinite permeability no mmf needed to set up flux), windings are having no resistances or reactances.
Isolating transformer theory?
Transformers use magnetic induction between 2 coils of wire to produce a voltage in the secondary winding. Typically the main purpose of a transformer is to step up or down the voltage by having differing number of windings between the primary and secondary coils. A secondary effect is to keep the 2 systems electrically isolated from eachother. If one of the phases becomes grounded, the ground is only seen on the portion of the system downstream of the transformer, thus increasing relibability.
How can the organization benefits from having an induction?

Is it right for someoneto ignore the duty of hajj inspite of his being able to perform it?
No, A Muslim should not ignore the duty of hajj inspite of his being able to to perform it because Prophet is reported to have said " He who dies without having performed the let him die a Jew or a christian as he wishes.
Why is the efficiency of a three-phase induction motor about 85-87percentage?
Not always. I have seen induction motors for various applications having efficiency upto 95%.
Which station was Mohandas Karamchand Gandhi thrown out of for not moving into the 3RD class compartment inspite of still having a 1st class ticket?
Pietermaritzburg railway station
How the secondary voltage in transformer is stepped up?
The secondary voltage in a transformer is stepped up by having more turns in the secondary coil compared to the primary coil. This creates a higher electromagnetic induction which leads to a higher output voltage. The ratio of the number of turns in the primary coil to the number of turns in the secondary coil determines the degree of voltage stepping up.
How does a transformer work on a 120 volt coil contactor with 220 volt feed?
A transformer works by utilizing electromagnetic induction to convert voltage levels between circuits. In the case of a 120-volt coil contactor connected to a 220-volt feed, the transformer steps down the voltage from 220 volts to 120 volts. This is achieved by having a primary winding connected to the 220-volt feed and a secondary winding with fewer turns of wire that supplies the 120-volt output, allowing the contactor to operate safely and effectively without being damaged by the higher voltage.
Is an animal of ape family is a vegetarian inspite of having strong teeth?
All the big apes are mainly herbivores - plant eaters - but particularly the Chimpanzees will happily eat meat when they can get it.
