Ideal Transformer Calculator

Ideal transformer calculator is an easy-to-use online tool which helps engineers to determine the parameters of the ideal transformer. A transformer has two coils (primary and secondary) to transfer the energy from one circuit to another. In the ideal transformer all the magnetic field from the primary coil passes through the secondary coil, i.e. the ideal transformer has no power loss.

This tool uses the following equation to calculate the voltage at the secondary coil:

Vs = Vp × Ns / Np,

where: Vs – voltage at the secondary coil, Vp – voltage at the primary coil, Ns – number of windings of the secondary coil, Np – number of windings of the primary coil.

The current at the secondary coil can be calculated using the following equation:

Is = Ip × Np / Ns,

where: Is – current at the secondary coil, Ip – current at the primary coil, Np – number of windings of the primary coil, Ns – number of windings of the secondary coil.


Frequently Asked Questions

  • How to calculate the secondary voltage for a step-down transformer?
  • How to calculate the secondary voltage for a step-down transformer?

    Just enter number of windings of the primary and secondary coils and primary voltage, for example:

    • Primary windings: 500 turns;
    • Secondary windings: 100 turns;
    • Primary voltage: 230 V.

    The calculator shows the secondary voltage will be 46 V.
