Inductance Calculator
Calculate total inductance for Series or Parallel circuits.
Series inductors add up (L1 + L2 + ...)
Enter values in the same unit (e.g. mH).
Inductor Formulas
Series Inductors
When inductors are connected in series, the total inductance is the sum of individual inductances (assuming no mutual inductance coupling).
L_total = L1 + L2 + L3 + ...
Parallel Inductors
When connected in parallel, the total inductance follows the same rule as resistors in parallel.
1/L_total = 1/L1 + 1/L2 + 1/L3 + ...
