Series Inductor Calculator Formula
Understand the math behind the series inductor calculator. Each variable explained with a worked example.
Formulas Used
Total Inductance
total_l = l1_mh + l2_mh + l3_mhVariables
| Variable | Description | Default |
|---|---|---|
l1_mh | Inductor L1(mH) | 10 |
l2_mh | Inductor L2(mH) | 22 |
l3_mh | Inductor L3 (0 to skip)(mH) | 0 |
How It Works
Series Inductors
L_total = L1 + L2 + L3 + ...
Inductances add directly in series, just like resistors in series. Assumes no mutual coupling.
Worked Example
10 mH and 22 mH in series.
l1_mh = 10l2_mh = 22l3_mh = 0
- 01L_total = 10 + 22 = 32 mH
Frequently Asked Questions
Do series inductors always add?
Yes, assuming no magnetic coupling. With coupling, mutual inductance adds or subtracts depending on orientation.
Why series instead of one larger inductor?
To achieve non-standard values or distribute heat across components.
Current through series inductors?
Same current flows through all, just like series resistors.
