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

Inductors connected in parallel combine their values using the same reciprocal formula as resistors in parallel. The total effective inductance of a parallel circuit is always less than the smallest individual inductor in that group. When two inductors of the exact same value are wired in parallel, the total effective inductance becomes exactly half of a single inductor's value. Choosing 'twice the value' is incorrect because that rule applies to inductors in series, not parallel.
