Formula: Parallel circuit (inductance)
Two coils connected in parallel

Total Inductance

Unit
Total inductance of \(n\) coils connected in parallel. The individual inductances of all coils connected in parallel add reciprocally.

For two coils connected in parallel (\(n=2\)), the reciprocal total inductance \(L\) is the reciprocal sum of the two individual inductances: $$ \frac{1}{L} ~=~ \frac{1}{L_1} ~+~ \frac{1}{L_2} $$ or rearranged for \( L \): $$ L ~=~ \frac{L_1 \, L_2}{L_1 + L_2} $$

Individual Inductance

Unit
Induktivitäten einzelner, parallel geschalteter Spulen. \(L_1\) ist die Induktivität der ersten Spule, \(L_2\) die Induktivität der zweiten Spule und so weiter. \(L_n\) ist die Induktivität der letzten, \(n\)-ten Spule.
