1. What is Equivalent Inductance?

Equivalent inductance (L_eq) is the total inductance of a circuit when multiple inductors are combined in series or parallel. It simplifies complex inductor networks into a single equivalent value.

2. How Does the Calculator Work?

The calculator uses these formulas:

Where:

• \( L_{eq} \) — Equivalent inductance (H)
• \( L_1, L_2, \ldots, L_n \) — Individual inductances (H)

Explanation: In series, inductances add directly. In parallel, their reciprocals add and the result is inverted.

3. Importance of Equivalent Inductance

Details: Calculating equivalent inductance is essential for circuit analysis, filter design, and understanding energy storage in inductive networks.

4. Using the Calculator

Tips: Select connection type (series/parallel) and enter comma-separated inductance values in henries (H). Example: "0.5, 1.2, 3.3"

5. Frequently Asked Questions (FAQ)

Q1: How does mutual inductance affect the calculation?
A: These formulas assume no mutual inductance between coils. With mutual inductance, more complex formulas are needed.

Q2: What happens if I enter 0 H for an inductor?
A: In series, 0 H would make the total 0 H. In parallel, 0 H would be ignored in the calculation.

Q3: Can I mix different units?
A: No, all values must be in the same unit (preferably henries). Convert mH or μH to H first.

Q4: How accurate is this calculation?
A: Perfectly accurate for ideal inductors without mutual coupling. Real-world factors like resistance and core effects may cause deviations.

Q5: What's the difference between series and parallel results?
A: Series always increases total inductance, while parallel decreases it compared to the smallest individual inductor.
