Parallel Inductor Calculator Formula
Understand the math behind the parallel inductor calculator. Each variable explained with a worked example.
Formulas Used
Total Inductance
total_l = 1 / (1/l1_mh + 1/l2_mh)Variables
| Variable | Description | Default |
|---|---|---|
l1_mh | Inductor L1(mH) | 10 |
l2_mh | Inductor L2(mH) | 22 |
How It Works
Parallel Inductors
1/L_total = 1/L1 + 1/L2
Same formula as parallel resistors. Assumes no mutual coupling between inductors.
Worked Example
10 mH and 22 mH in parallel.
l1_mh = 10l2_mh = 22
- 011/L = 1/10 + 1/22 = 0.1 + 0.04545 = 0.14545
- 02L_total = 6.875 mH
