Why does a transformer require ac? Transformer: A transformer is a device normally used to step up or down AC power and rarely to isolate circuits. The principle of operation of a transformer is mutual inductance between the electrically separate input and output coils. Answer and Explanation: ...
Compared to a regular transformer, there's additional phase shift due to rotor slip angle. The motor acts just like a 1:1 transformer would, less phase shift, with two additional transductions in series with energy flow: magnetic to mechanical on phase 1 ("primary"), and mechanical to magne...
How a transformer works is based on the ratio of coils of one side to the other. The side that has a greater of amount of turns relative to the other will have a larger voltage. So, a step-down transformer has a greater amount of turns at the primary side than the secondary side. ...

of the transformer led to the development of constant power ac supply systems. before the invention of the transformer, dc systems were used for the supply of electricity. installation of the power transformers made the distribution system more flexible and more efficient. what is a transformer?
