If two equal-value inductors are connected in series, what is their total inductance?

Inductors in a series circuit combine their values in the exact same way that resistors in series do. You simply add their individual inductance values together to find the total. When two inductors of the same value are connected end-to-end (in series), the total inductance is simply one value plus the other, effectively doubling the original value. Distractors suggesting the value is halved or divided apply to parallel circuits or capacitors, not inductors in series.
