Series Inductor Calculator
Series Inductor converts the entered electrical measurements into equivalent inductance. Use it to the equivalent inductance calculation.
Enter values for equivalent inductance
Use one consistent electrical operating case for all fields.
How Series Inductor works
This worksheet evaluates Leq = L1 + L2. Series Inductor uses Inductor L1, Inductor L2 to report Equivalent inductance. For stored energy, use Capacitor Energy Calculator.
With the loaded values, equivalent inductance evaluates to 32.00 mH. Use separate cases for competing input values.
Inputs for Series Inductor
Inductor L1 and Inductor L2 belong to Series Inductor. Keep source units with inductor l1.
Use the defaults to understand the output, then enter the real circuit or energy data. Compare this result with BJT Bias Calculator when base current is also needed.
- Inductor L1
- Example entry: 10 mH.
- Inductor L2
- Example entry: 22 mH.
Reading the Series Inductor result
This output represents Series Inductor.
Compare the output with equipment limits and the applicable design margins.
Measurement and units
Use component tolerances, voltage ratings, current limits, frequency behavior, and thermal data from the selected parts. Check prefixes on inductor l1.
Do not compare cases built from different unit prefixes or measurement locations.
Limits of this calculation
Mutual coupling is assumed negligible.
Unlisted circuit behavior remains outside the computed result. Unentered effects remain outside Series Inductor.
Questions about Series Inductor
What does Series Inductor calculate?
It evaluates equivalent inductance from inductor L1 and inductor L2 using the displayed formula.
Can Inductor L1 be zero?
For Series Inductor, measure any zero inductor l1 directly.
Why can equivalent inductance differ from measurement?
Mutual coupling is assumed negligible. Recheck inductor l1.
Should the result be rounded?
Keep extra digits while comparing cases, then round to the precision supported by inductor L1.
