What is the Transformer Calculator?

The Transformer Calculator is a practical tool that helps students, engineers, and electronics enthusiasts analyze transformers by calculating unknown values such as primary voltage, secondary voltage, or number of turns based on known parameters. By entering at least three known values—primary voltage, secondary voltage, primary turns, or secondary turns—the calculator determines the missing value and provides the voltage and turns ratios. It also indicates whether the transformer is step-up or step-down, helping users design, test, or understand transformer behavior efficiently without manual calculations.

How to Use:

1. Enter Known Values: Input at least three of the four parameters: primary voltage (V₁), secondary voltage (V₂), primary turns (N₁), or secondary turns (N₂). Leave the value you want to calculate blank.
2. Click “Calculate”: The calculator uses the transformer formula V₁ / V₂ = N₁ / N₂ to compute the missing value and the voltage/turns ratios.
3. Review Result: The output shows the calculated value, the ratios of voltage and turns, the transformer type (step-up or step-down), and the formula used, allowing you to quickly understand transformer relationships and make accurate design decisions.
