The result shows the total inductance. The total is the sum of all individual inductances.

Formula

Ltotal = L1 + L2 + L3 + ...

Where:

  • Ltotal = Total inductance (H)
  • L1, L2, L3 = Individual inductances (H)

Key Points:

  • Series connection increases total inductance
  • Total inductance is the sum of all individual inductances
  • Similar to series resistors - inductances add directly

Example:

Inductors: 100 µH, 200 µH, 300 µH

Ltotal = 100 + 200 + 300 = 600 µH

Frequently Asked Questions

Why does series connection increase inductance?

When inductors are in series, their magnetic fields add together, increasing the total inductance. The total is simply the sum of all individual inductances, similar to series resistors.

What if I have equal inductors?

For n equal inductors in series, total inductance = n × L. For example, three 100µH inductors in series give 300µH total.

Does mutual inductance affect series inductors?

If inductors are magnetically coupled (close together), mutual inductance affects the calculation. For isolated inductors (no coupling), the formula is simply the sum. This calculator assumes no coupling.
