Transformer Calculator
Calculate transformer turns ratio, secondary voltage, and current. Supports calculation from voltage ratio or turns count. Shows step-up/step-down type and apparent power.
How to Use Transformer Calculator
Enter primary and secondary voltages to calculate turns ratio, or enter turns counts to derive voltages. Optionally add power rating in VA to calculate currents. The calculator determines if the transformer is step-up or step-down.
Step-by-Step Instructions
- Enter primary and/or secondary voltage
