1. What is Parallel Inductance?

When inductors are connected in parallel, their combined inductance is less than any individual inductor's inductance. The equivalent inductance (L_eq) is calculated using the reciprocal formula.

2. How Does the Calculator Work?

The calculator uses the parallel inductance formula:

Where:

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

Explanation: The reciprocal of the total inductance equals the sum of reciprocals of individual inductances in parallel.

3. Importance of Parallel Inductance Calculation

Details: Calculating equivalent parallel inductance is essential for circuit design, analyzing filter networks, and designing inductive components in electronic systems.

4. Using the Calculator

Tips: Enter at least two inductance values in henries (H). All values must be positive numbers. The calculator can handle two or three parallel inductors.

5. Frequently Asked Questions (FAQ)

Q1: What happens when identical inductors are connected in parallel?
A: For N identical inductors L in parallel, the equivalent inductance is L/N.

Q2: How does parallel inductance compare to series inductance?
A: Parallel connection decreases total inductance, while series connection increases it (L_series = L₁ + L₂ + ...).

Q3: Does mutual inductance affect parallel inductance calculations?
A: Yes, if inductors are coupled (share magnetic flux), additional terms for mutual inductance must be included.

Q4: What are typical applications of parallel inductors?
A: Used in power electronics, RF circuits, and where specific inductance values with higher current capacity are needed.

Q5: How does parallel connection affect inductor current?
A: Current divides among parallel inductors inversely proportional to their inductance values (higher inductance gets less current).
