1. What is Series Inductance?

When inductors are connected in series, their total inductance is the sum of the individual inductances. This is different from parallel connections where the reciprocal of the total inductance is the sum of reciprocals of individual inductances.

2. How Does the Calculator Work?

The calculator uses the series inductance formula:

Where:

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

Explanation: In series connection, the same current flows through all inductors, and their inductances simply add up.

3. Importance of Series Inductance Calculation

Details: Calculating equivalent inductance is crucial for circuit design, filter creation, and understanding energy storage in inductive circuits.

4. Using the Calculator

Tips: Enter inductance values in henries (H). You can calculate with 2 or 3 inductors (leave third field blank if not needed). All values must be non-negative.

5. Frequently Asked Questions (FAQ)

Q1: Does the order of series inductors matter?
A: No, the total inductance is the same regardless of the order of the inductors in series.

Q2: What happens if inductors are not ideal?
A: Real inductors have resistance and capacitance that may affect the circuit behavior, especially at high frequencies.

Q3: Can I add more than 3 inductors?
A: Yes, the same principle applies - just sum all inductances. You can chain calculations by using the result as one inductor in another calculation.

Q4: What about mutual inductance?
A: This calculator assumes no mutual coupling between inductors. If inductors are coupled, additional terms would be needed in the calculation.

Q5: How does this compare to capacitors in series?
A: Inductors in series add directly, while capacitors in series combine like resistors in parallel (reciprocal of sum of reciprocals).
