Two indentical coils, each of inductance `L`, are interconnected (a) in series, (b) in parallel. Assuminng the mutual insducane of the coils to be negliglible, find the inductance fo the system in both cases.

An inductor of inductance L is cut in three equal parts and two of these parts are interconnected (a) in series, (b) in parallel. Assuming the mutual inductance between the parts to be negligible, calculate the inductance of the combination of the combination in both the cases.
