1. What is Series Inductance?

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

2. How Does the Calculator Work?

The calculator uses the series inductance formula:

Where:

• \( L_{eq} \) — Equivalent series inductance (H)
• \( L_1 \) — First inductance value (H)
• \( L_2 \) — Second inductance value (H)

Explanation: The total inductance in series is simply the arithmetic sum of all individual inductances in the series connection.

3. Importance of Series Inductance Calculation

Details: Calculating equivalent series inductance is essential for circuit design, filter creation, and understanding how inductors will behave in series configurations.

4. Using the Calculator

Tips: Enter both inductance values in henries (H). The calculator will sum them to give the total series inductance.

5. Frequently Asked Questions (FAQ)

Q1: Does the order of series connection matter?
A: No, the order of inductors in series doesn't affect the total inductance, as long as there's no mutual coupling between them.

Q2: What if I have more than two inductors?
A: The same principle applies - simply add all inductance values together: \( L_{eq} = L_1 + L_2 + L_3 + ... \)

Q3: How does series inductance compare to parallel?
A: Series inductance increases total inductance, while parallel connections decrease it (similar to resistors but opposite to capacitors).

Q4: What about mutual inductance between coils?
A: This calculator assumes no mutual coupling. If mutual inductance exists, the calculation becomes more complex.

Q5: What units should I use?
A: The calculator uses henries (H), but you can use any consistent units (mH, μH) as long as all values are in the same unit.
