1. What Is Series Inductance?

Series inductance refers to the total inductance when multiple inductors are connected end-to-end in a series configuration. The total inductance is simply the sum of all individual inductances in the circuit.

2. How Does The Calculator Work?

The calculator uses the series inductance formula:

Where:

• \( L_T \) — Total inductance (H)
• \( L_1, L_2, \ldots, L_n \) — Individual inductances (H)

Explanation: When inductors are connected in series, their inductances add up directly without any complex interactions, unlike capacitors in series.

3. Importance Of Series Inductance Calculation

Details: Calculating total series inductance is essential for designing electronic circuits, filters, power supplies, and RF applications where specific inductance values are required.

4. Using The Calculator

Tips: Enter inductance values in henries (H). You can calculate with 2-4 inductors. For more than 4 inductors, simply add the additional values to the result manually.

5. Frequently Asked Questions (FAQ)

Q1: Why do inductors in series add directly?
A: Unlike capacitors, inductors in series experience the same current, and their magnetic fields combine constructively, resulting in simple addition of inductance values.

Q2: What is the unit of inductance?
A: The standard unit is the henry (H), though millihenries (mH) and microhenries (μH) are commonly used for smaller values.

Q3: Does mutual inductance affect series calculations?
A: This calculator assumes no mutual inductance between inductors. If mutual inductance exists, the calculation becomes more complex.

Q4: Can I mix different types of inductors in series?
A: Yes, different types of inductors (air core, iron core, toroidal) can be connected in series, and their inductances will still add directly.

Q5: What about inductors in parallel?
A: Inductors in parallel follow a reciprocal formula similar to resistors in parallel: \( \frac{1}{L_T} = \frac{1}{L_1} + \frac{1}{L_2} + \cdots + \frac{1}{L_n} \)
