Free Transformer Turns Ratio
Calculate the primary-to-secondary turns ratio based on input and output voltages. A fundamental tool for transformer rewinding and testing.
Configuration
How to Use
- Enter the Primary (Input) Voltage.
- Enter the Secondary (Output) Voltage.
- The result shows the Turns Ratio (N1:N2), which equals the Voltage Ratio.
Common Use Cases
- Testing
Frequently Asked Questions
What does the turns ratio tell me?
It tells you the relationship between input and output. A 10:1 ratio means the input voltage is stepped down by a factor of 10.
Does this apply to current?
Yes, but inversely. A transformer that steps voltage DOWN by 10x will step current UP by 10x (ignoring losses).
