How it works
Ideal secondary voltage = primary voltage × secondary turns / primary turns.
Input definitions
- Primary voltage (V RMS)
- Enter the value in the labeled unit.
- Primary turns
- Enter the value in the labeled unit.
- Secondary turns
- Enter the value in the labeled unit.
A worked example
- Primary voltage (V RMS)
- 230
- Primary turns
- 1000
- Secondary turns
- 100

Common questions
Does this predict a loaded real transformer exactly?
No. Winding resistance, leakage inductance, core losses, regulation and safety isolation requirements are not included.
How does Ideal transformer secondary voltage work?
Ideal secondary voltage = primary voltage × secondary turns / primary turns.
What should I check before using Ideal transformer secondary voltage?
Ideal educational model in the stated SI units. Real equipment, structural design and safety decisions need appropriate professional analysis; losses are excluded unless entered.
