<p>The author obtains a complete solution of the problem of coupled circuits-direct-coupled circuits as well as those coupled electromagnetically-by a method which avoids the difficulty of getting the roots of a biquadratic equation. Both cases are fully worked out. The paper is altogether mathematical and cannot be abstracted.
