Parallel Inductance Formula:
From: | To: |
Definition: This calculator computes the equivalent inductance of multiple inductors connected in parallel.
Purpose: It helps electrical engineers, technicians, and students determine the combined inductance when inductors are connected in parallel.
The calculator uses the formula:
Where:
Explanation: The reciprocal of the total inductance equals the sum of the reciprocals of all individual inductances in parallel.
Details: Proper inductance calculation is crucial for circuit design, ensuring desired performance in filters, transformers, and energy storage applications.
Tips: Enter all inductance values separated by commas (e.g., "0.5, 1.2, 0.3"). All values must be > 0.
Q1: Why do we use reciprocals for parallel inductance?
A: This method accounts for how parallel inductances combine similarly to parallel resistances, following the same mathematical relationship.
Q2: What happens if one inductor is much smaller than others?
A: The total inductance will be close to the smallest inductance value, as it dominates the parallel combination.
Q3: Does mutual inductance affect this calculation?
A: This calculator assumes no mutual inductance between coils. If mutual inductance exists, additional calculations are needed.
Q4: What units should I use?
A: Use consistent units (typically henrys) for all inductances. The result will be in the same units.
Q5: How does this compare to series inductance?
A: Series inductances simply add together (L_total = L1 + L2 + ...), while parallel inductances combine through reciprocal sums.
