Inductors in Series Calculator

In a series circuit, inductors add together directly. The total inductance equals the sum of all individual inductances: Lt = L1 + L2 + L3 + ... This is because the same current flows through all inductors in series.

Three 10 mH inductors in series would have a total inductance of 30 mH (10 + 10 + 10 = 30). Each inductor contributes its full value to the total when connected in series.

When two inductors are connected in series, their inductances add together. The total inductance increases, and the same current flows through both inductors, but the voltage drop across each depends on its individual inductance value.

Inductors store energy in their magnetic field and oppose changes in current flow. They are characterized by inductance (measured in henries), which determines how much they resist current changes. Higher inductance means stronger opposition to current changes.

In series, inductors add together (Lt = L1 + L2 + ...), increasing total inductance. In parallel, the reciprocal formula applies (1/Lt = 1/L1 + 1/L2 + ...), decreasing total inductance. Series connection increases inductance while parallel connection decreases it.

Yes, but all values must be converted to the same unit before adding. Our calculator handles this automatically - you can input each inductor in its most convenient unit (nH, µH, mH, H, kH) and get accurate results.

Series inductors are used in filter circuits, impedance matching networks, RF circuits, and power supplies. They're commonly found in chokes, transformers, and tuned circuits where higher inductance values are needed than a single inductor can provide.

No, the order doesn't affect the total inductance calculation. Whether you arrange them as L1-L2-L3 or L3-L1-L2, the total inductance remains the same because addition is commutative. However, physical placement may affect other circuit characteristics like stray capacitance.
