Inductor Series Parallel
A precise tool.
What is the Inductor Series Parallel & How does it work?
Inductors store energy in a magnetic field, and their ability to oppose changes in current is quantified by inductance (L). When multiple inductors are connected, the total inductance depends on whether they are arranged in series or parallel, analogous to resistors but with opposite combination rules.
In a series connection, the same current flows through each inductor, so the magnetic fields add linearly. The total series inductance is simply the arithmetic sum of the individual values:
In a parallel configuration, the voltage across each inductor is identical, and the total inductance is found by summing the reciprocals of each inductance, then taking the reciprocal of that sum, yielding a lower overall inductance: L_{\text{parallel}} = \left( \sum_{i=1}^{N} \frac{1}{L_i} \right)^{-1}
L_{\text{series}} = \sum_{i=1}^{N} L_i
L_{series} = total series inductance

Frequently Asked Questions
How do I calculate total inductance in a series circuit?
To find the total inductance in a series circuit, simply add up the individual inductances: L_total = L1 + L2 + … + Ln.
What is the formula for parallel connected inductors?
For parallel connected inductors, use the formula 1/L_total = 1/L1 + 1/L2 + … + 1/Ln to find the total inductance.
How does adding more inductors in series affect the total inductance?
Adding more inductors in series increases the total inductance because it’s simply the sum of all individual inductances.
Can I use this calculator for both series and parallel inductors?
Yes, you can use this calculator to calculate the total inductance for both series and parallel configurations of inductors.
What is the difference between series and parallel inductance calculations?
Series inductance adds up the individual values (L_total = L1 + L2), while parallel inductance uses the reciprocal sum formula (1/L_total = 1/L1 + 1/L2).
How does temperature affect inductor inductance?
Temperature can slightly change an inductor’s inductance, typically increasing it. This effect is usually small and depends on the specific material used.
Can I use this calculator for capacitors too?
No, this calculator is specifically for inductors. For capacitors, you would need a different type of calculator that handles capacitance calculations.
