Formula and methodology
Formula: V2/V1=N2/N1; I2/I1=N1/N2 under ideal power conservation.
The turns ratio, voltage, current, and ideal power check are shown separately from real transformer losses.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Primary turns — minimum 1; maximum 1000000000
- Secondary turns — minimum 1; maximum 1000000000
- Primary voltage — minimum 0; maximum 1000000000
- Primary current — minimum 0; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Primary turns | 1000 |
| Secondary turns | 100 |
| Primary voltage | 120 |
| Primary current | 1 |
Secondary voltage =12 V; secondary current =10 A.
Assumptions and limits
- Turns, voltage, and current are positive or nonnegative under one AC convention.
- The transformer is ideal with no leakage, copper loss, core loss, or saturation.
- Frequency, insulation, regulation, heating, and equipment ratings are not modeled.
