A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. A varying current in one coil of the transformer produces a varying magnetic field, which in turn induces a voltage in a second coil. Power can be transferred between the two coils through the magnetic field, without a metallic connection between the two circuits.
A transformer's 'transformation ratio' applies, whether it is a step-up, or a step-down, transformer. It is normally expressed as its turns ratio, Ns/Np, where N = number of t â¦ urns. For an ideal transformer, it can also be expressed as the voltage ratio, which is Vs/Vp (where p = primary, and s = secondary).hen the output voltage is higher than the input voltage that is considered a step up transformer. When the output is less than the input you have a step down transformer.
