Transformers exist in real life, but they don’t quite resemble the robots from the movie. Learn about real transformers and how these robots are used. Advertisement By: Tracy V. Wilson Without a doubt, the HowStuffWorks staff is anxious a

A transformer is based on a very simple fact about electricity: when a fluctuating electric current flows through a wire, it generates a magnetic field (an invisible pattern of magnetism) or "magnetic flux" all around it.The strength of the magnetism (which has the rather technical name of magnetic flux density) is directly related to the size of the electric current. Why Transformers Only Works With Alternating Current The main coil is linked to an AC supply. AN AC flows through a main coil wrapped around a soft iron core The altering current generates a changing magnetic field. This makes an alternating voltage in the minor coil. This makes an AC in the circuit Transformers are useful devices and learning how to design and work with them can come in very handy!
2020-12-28 2020-01-13 A transformer works because A. electricity flows from a primary coil to a secondary coil. B. electricity is induced in a rotating coil. C. a changing magnetic field is transferred to a coil via an iron core. D. electricity is transferred to a coil via an iron core. Electrical transformers are machines that transfer electricity from one circuit to another with changing voltage level but no frequency change. Today, they are designed to use AC supply, which means that fluctuation in supply voltage is impacted by the fluctuation in the current. The primary and secondary winding of the transformer are wound on a magnetic strip and the flux linkage between them is through the air.
For a transformer to work, the current in one coil has to somehow make current flow in the other coil and the circuit it's connected to. A DC current in one coil will make a magnetic field on the other coil, but a magnetic field by itself won't drive any electrons around.
mutual induction. A Transformer operates when both circuits take effect by mutual induction. A Transformer can’t step-up or step-down the level of DC voltage or DC Current.

It will "work" in a sense, just as any other transformer, but as the flux circuit is only closed by magnetic field leakage from one end of the core to the other, its reluctance will be enormous, and therefore it'll be much less efficient than you would like.
An electrical transformer uses Faraday’s electromagnetic induction law to work – “Rate of change of flux linkage with respect to time is directly proportional to the induced EMF in a conductor or coil”.

Complete protection is achieved by this cast resin encapsulation so that the transformer can work without disruption There is no simple way of changing DC voltage levels. Because of its time-varying magnetic field, the AC system allows the use of the transformer to change voltage levels as needed.

B) A Transformer Operates On Direct Current As Well As On Alternating Current. C) A Transformer Works Because Changing Magnetic Fields Can Induce Electric Fields. D) Transformers Are Commonly Used For Delivering Also, transformers work on AC, not DC, so the actual voltages are constantly changing with respect to each other in time. 0V is a relative term in AC. In fact, at 60Hz, A and G alternate being 0V 60 times a second. But it's convenient to think of the voltages as a magnitude, like when we put a DMM on said transformer and measure it. A transformer is a device that uses the principles of electromagnetism to convert one voltage or current to another.
