Final answer:
The equivalent inductance for n inductors connected in series with individual inductances L1, L2, ... Ln is obtained by adding the individual inductance values together.
Step-by-step explanation:
The equation that gives the equivalent inductance for n inductors connected in series with individual inductances L1, L2, ... Ln is:
Leq = L1 + L2 + ... + Ln
When inductors are connected in series, their total inductance is the sum of their individual inductances. Therefore, you can simply add the individual inductance values together to get the equivalent inductance.
