1. What is Parallel Inductance?

When inductors are connected in parallel, their combined inductance is less than any of the individual inductances. 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:

• \( L1 \) — Inductance of first inductor (Henries)
• \( L2 \) — Inductance of second inductor (Henries)

Explanation: The formula shows that the equivalent inductance of two parallel inductors is the product divided by the sum of the individual inductances.

3. Importance of Parallel Inductance Calculation

Details: Calculating equivalent parallel inductance is essential for circuit design, filter networks, and understanding how inductors combine in electronic circuits.

4. Using the Calculator

Tips: Enter both inductance values in Henries (H). All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: Does this formula work for more than two inductors?
A: For more than two parallel inductors, use the reciprocal formula: 1/L_eq = 1/L1 + 1/L2 + 1/L3 + ...

Q2: What if one inductor is much larger than the other?
A: The equivalent inductance will be close to the value of the smaller inductor.

Q3: How does mutual inductance affect this calculation?
A: This formula assumes no mutual inductance between coils. If mutual inductance exists, more complex calculations are needed.

Q4: What are typical inductor values?
A: Inductors range from nanohenries (nH) for high-frequency circuits to henries (H) for power applications.

Q5: Can I parallel inductors to increase current capacity?
A: Yes, paralleling inductors can increase current handling while reducing equivalent inductance.
