The transformer winding formula only holds true when the angles of primary and secondary windings are in phase with one another.

This means the transformer turns ratio will always be positive, but can vary between being greater than one for step-up transformers or less than one for step-down transformers.

Transformers can increase or decrease voltage, and are known as step-up or step-down transformers depending on which action they perform. But the ratio means that, for one of something, there are four of something else, which doesn't always mean the same thing as a fraction. Keep in mind that, although this formula is referred to as 'ratio,' it is actually a fraction, not a ratio. This transformer winding formula tells you the fraction by which a transformer changes incoming voltage and that the voltage of the winds of a coil is directly proportional to the number of windings of the coils themselves. The transformers that power grid distributions systems use follow simple designs that use coil wound around a magnetic core in different areas. These transformers use simple designs across most types of transformers, but can vary greatly in how much they change input voltage based on how they're built. In a step-up transformer, the primary voltage can be stepped up based on the turns ratio but the load current capability of the same at the stepped-up voltage will reduce as the inverse of the turns ratio.If you've ever wondered how houses and buildings use the electricity from power plants, you should learn about the transformers in power grid distributions which convert high-voltage currents to the ones you use in household appliances. Hence for an ideal transformer, the output current varies as the inversely proportional to the voltage. Therefore, V p / N p = V s / N s and V p / V s = N p / N s Relationship between Turns ratio and currentįor an ideal transformer, the input power is always equal to the output voltage. Where k is a constant and φ m is the maximum flux. Let Vp be the voltage applied to the primary at a frequency of ‘f’, the Vp be the voltage measured at the secondary. For an ideal transformer, consider an ideal transformer with Np number of turns in the primary and Ns number of turns in the secondary. An ideal transformer is assumed to have zero winding impedance, zero leakage flux, and zero losses.
