1. What is an Inductor Series Calculator?

Definition: This calculator computes the total inductance of inductors connected in series in an electrical circuit.

Purpose: It helps electronics engineers, technicians, and hobbyists determine the combined inductance when multiple inductors are connected in series.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( L_{total} \) — Total inductance (henrys)
• \( L_1, L_2, \ldots, L_n \) — Individual inductances (henrys)

Explanation: In a series connection, the total inductance is simply the sum of all individual inductances.

3. Importance of Series Inductance Calculation

Details: Proper inductance calculation is crucial for designing filters, oscillators, power supplies, and other electronic circuits where precise inductance values are required.

4. Using the Calculator

Tips: Enter the inductance values for each inductor in henrys (H). You must provide at least two values. All values must be ≥ 0.

5. Frequently Asked Questions (FAQ)

Q1: What happens if I leave some inductor fields blank?
A: Only the first two fields are required. Blank fields are treated as 0 henrys.

Q2: What units does this calculator use?
A: All calculations are done in henrys (H), the SI unit of inductance.

Q3: Does this work for air-core and iron-core inductors?
A: Yes, the series inductance formula applies to all types of inductors.

Q4: How does this differ from parallel inductance calculation?
A: Parallel inductors use reciprocal summing (1/L_total = 1/L₁ + 1/L₂ + ...).

Q5: What's the practical limit for series inductors?
A: While you can sum any number of inductors, practical circuits consider physical size, resistance, and self-resonance.
