Electrical Inductance - Serial and Parallel Connections
Calculate electrical inductance in serial and parallel connected inductors. Choose between serial connection (L = L1 + L2 + ... + Ln) or parallel connection (1/L = 1/L1 + 1/L2 + ... + 1/Ln).
Formula Reference
Serial Connection (Equation 1)
L = L1 + L2 + ... + Ln
Where:
- L = Total inductance (henrys, H)
- L1, L2, ..., Ln = Individual inductances in series
In serial connection, inductances add directly.
Parallel Connection (Equation 2)
1/L = 1/L1 + 1/L2 + ... + 1/Ln
Where:
- L = Total inductance (henrys, H)
- L1, L2, ..., Ln = Individual inductances in parallel
In parallel connection, the reciprocals of inductances add up. The total inductance is always less than the smallest individual inductance.
