1. What is a Series and Parallel Inductor Calculator?

Definition: This calculator computes the total inductance for multiple inductors connected either in series or parallel configuration.

Purpose: It helps electronics engineers, students, and hobbyists determine the effective inductance in circuits with multiple inductors.

2. How Does the Calculator Work?

The calculator uses different formulas based on the connection type:

Where:

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

Explanation: In series, inductances add directly. In parallel, the reciprocals of inductances add together, then you take the reciprocal of the sum.

3. Importance of Inductance Calculation

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

4. Using the Calculator

Tips: Enter comma-separated inductor values in henrys (e.g., "0.001, 0.002, 0.003") and select the connection type. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between series and parallel connection?
A: In series, inductors are connected end-to-end (current flows through all). In parallel, inductors are connected across the same two points.

Q2: What units should I use for the inductors?
A: The calculator uses henrys (H), but you can enter values in millihenrys (mH) or microhenrys (μH) as decimals (e.g., 0.001 H = 1 mH).

Q3: Does mutual inductance affect these calculations?
A: These formulas assume no mutual inductance between coils. If inductors are coupled, different calculations are needed.

Q4: Why is parallel inductance less than any individual inductor?
A: Just like resistors in parallel, parallel inductors provide multiple paths for current, reducing the overall inductance.

Q5: How accurate are these calculations?
A: These are theoretical values. Real-world factors like inductor quality, frequency, and temperature may affect actual performance.
