A LITTLE CONTEXT
How to use transformer calculator
- Enter or edit the example values in the input panel.
- Review the method below and choose the options that match your task.
- Run the tool, check the result, and copy or download it. Reset restores the example; Clear removes your input and result.
Method & assumptions
Ideal transformer: Vₛ = Vₚ × Nₛ/Nₚ, where Nₚ and Nₛ are positive whole turns.
This is an ideal AC transformer turns-ratio estimate, with no winding losses, saturation, load regulation or current limit. It is not a wiring or equipment-rating recommendation.
Result units: Ideal secondary voltage (V)
Worked example
