what is transformer? what is transformation ratio ?
Answers
Explanation:
A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to one or more circuits.
It is actually defined for a transformer. Transformation Ratio (K) is defined as the ratio of the EMF in the secondary coil to that in the primary coil.
Answer:
A transformer is an electrical device which, by the principles of electromagnetic induction, transfers electrical energy from one electric circuit to another, without changing the frequency. ... Transformers either increases or decreases AC voltage. Transformers are used to meet a wide variety of needs.
Transformation ratio is defined as the ratio of number of turns in the secondary winding to the number of turns in the primary winding. It also defined as the ratio of voltage at the secondary terminal to the voltage at the primary terminals.
