What is the difference between autotransformer and two winding transformer?
Main difference is that , that the auto_t is electrical based while the other t is based on mutual inductance.
What is the difference between transformers and autotransformers?
A transformer or, more-properly, a mutual transformer, has two windings, the primary and the secondary, which are electrically-isolated from each other, with the secondary voltage induced through mutual induction. An autotransformerconsists of one tapped winding, so the secondary circuit is not electrically isolated from the primary circuit. An autotransformer may be used to either increase or decrease the primary voltage, depending how it is connected.
A auto transformer has what kind of induction?
self-induction."According to Lenz's law,[6]a changing electric current through a circuit that contains inductance, induces a proportional voltage, which opposes the change in current (self-inductance). The varying field in this circuit may also induce an e.m.f. in neighbouring circuits (mutual inductance)." - Wikipedia
What is inductance and types of inductance?
inductor is a electronic component that resist a change in the flow of current inductance is that property of inductor.
What principle emf induces in secondary winding of transformer?
mutual inductance
What is an example of mutual inductance?
A transformer because, to work, it must use mutual inductance between its separate windings.

What is mutual coupling in transformer?
It stands for how does the primary and secondary winding magnetic fields connected firmly without much of leakage flux.
What device employs mutual induction?
Mutual inductance OR induction refers to two independent coils which are electrically isolated but magnetically coupled through a path of low reluctance .This will cause most of the energy produced in the primary side to transfer to the secondary with minimal losses.That is why transformers which functioning on the principle of mutual induction has efficiency nearly 99%.
Is the mutual inductance of a transformer is constant under all operating conditions?
The mutual inductance is defined as the voltage induced in one winding when the current in the other winding changes by one amp per second. In an AC system it is the open-circuit induced voltage in the secondary divided by 2 x pi x frequency times the current in the primary. The mutual inductance is determined by the size and shape of the transformer. However if the transformer is operated at more than the rated flux-density of the magnetic core material, the mutual inductance falls (for normal laminated iron cores the maximum flux density is 1 Weber per square metre).
What are the Example each for self induced and mutually induced emf?
if an emf is induced in a coil due to the current flowing through itself is called SELF INDUCTANCE. on the other hand if an emf is induced on another coil due to the current flowing through the previous coil then it is called MUTUAL INDUCTANCE. suppose there are two coils A and B a current is flowing through A. now if the flux produced due to this current induce an emf on the same coil A, then it is SELF INDUCTANCE, and if it produce emf on B, then it is MUTUAL INDUCTANCE due to coil A.
How transformer works?
Hi , It works on the principle that mutual induction between two coils.
How is works transformer?
Hi , It works on the principle that mutual induction between two coils.
What extremely useful device is based on the principle of mutual inductance?
Transformers are extremely useful devices based on the principle of mutual inductance, which is the process where a changing current in one coil induces a voltage in another coil. Transformers are widely used in electrical power distribution and transmission systems to change voltage levels efficiently.
What is the difference between autotransformer and two winding transformer?
Main difference is that , that the auto_t is electrical based while the other t is based on mutual inductance.
When did transformers come to the world?
