AC Inductor Reactance
Use this ac inductor reactance tool when you have measured values for frequency hz, inductance mh. It applies a transparent mathematical relationship to those values to return an answer in ohms. Unlike a prediction or recommendation, this is a calculation from your inputs. For ideal inductance at a single sinusoidal frequency. 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 frequency hz, inductance mh.
- Enter each quantity; blank, nonnumeric and out-of-range inputs are not accepted.
- Compare the reported ohms quantity against your own data and the limitations below.
Formula for AC Inductor Reactance
ohms = 2*π*frequency_hz*inductance_mh/1000. 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.
- For ideal inductance at a single sinusoidal frequency.
Worked examples
Worked example — AC Inductor Reactance
Enter Frequency hz = 50, Inductance mh = 85.
Apply 2*π*frequency_hz*inductance_mh/1000.
Calculated value: approximately 26.70354 ohms.
Understanding the result
The example produces about 26.70354 ohms; this is a mathematical output for the example inputs, not an observed result for your project.
For ideal inductance at a single sinusoidal frequency.
Important notes
For ideal inductance at a single sinusoidal frequency.
Use values from the same measurement period or physical system. The result is in ohms and is not a guarantee of capacity, safety, ranking or revenue.
