Transformer Ideal Secondary Voltage
Use this transformer ideal secondary voltage tool when you have measured values for primary volts, primary turns, secondary turns. It applies a transparent mathematical relationship to those values to return an answer in V. Unlike a prediction or recommendation, this is a calculation from your inputs. Ideal transformer ignores losses and saturation. Enter a different scenario to see how this particular quantity changes; check the assumptions before using it in a project.
How to use this calculator
- Use exact measurements and consistent units for primary volts, primary turns, secondary turns.
- Enter each quantity; blank, nonnumeric and out-of-range inputs are not accepted.
- Compare the reported V quantity against your own data and the limitations below.
Formula for Transformer Ideal Secondary Voltage
V = primary_volts*secondary_turns/primary_turns. Inputs are expressed in the units shown by the labels.
- This uses a direct electrical relationship and does not retrieve remote data, forecasts or individual account information.
- Ideal transformer ignores losses and saturation.
Worked examples
Worked example — Transformer Ideal Secondary Voltage
Enter Primary volts = 230, Primary turns = 920, Secondary turns = 48.
Apply primary_volts*secondary_turns/primary_turns.
Calculated value: approximately 12 V.
Understanding the result
The example produces about 12 V; this is a mathematical output for the example inputs, not an observed result for your project.
Ideal transformer ignores losses and saturation.
Important notes
Ideal transformer ignores losses and saturation.
Use values from the same measurement period or physical system. The result is in V and is not a guarantee of capacity, safety, ranking or revenue.
