Explanation:
A transformer is an electrical device that is used to transfer electrical energy from one circuit to another through electromagnetic induction. It has two coils, a primary coil and a secondary coil, and a magnetic core.
The voltage transformation ratio of a transformer is defined as the ratio of the secondary induced e.m.f. (electromotive force) to the primary induced e.m.f. In other words, it is the ratio of the output voltage to the input voltage.
Mathematically, the voltage transformation ratio (K) is given by:
K = E2 / E1
where E2 is the secondary induced e.m.f. and E1 is the primary induced e.m.f.
The voltage transformation ratio depends on the turns ratio of the transformer. The turns ratio is the ratio of the number of turns in the secondary coil to the number of turns in the primary coil.
Mathematically, the turns ratio (N) is given by:
N = N2 / N1
where N2 is the number of turns in the secondary coil and N1 is the number of turns in the primary coil.
Therefore, the voltage transformation ratio can also be expressed as:
K = N2 / N1
This means that the voltage transformation ratio of a transformer is directly proportional to the turns ratio of the transformer.
Conclusion:
The voltage transformation ratio of a transformer is the ratio of the secondary induced e.m.f. to the primary induced e.m.f. It is directly proportional to the turns ratio of the transformer.
