Total inductance in series = L1+L2+L3
2.2+3.3+0.2= 5.5

Total inductance in series = L1+L2+L3
2 + 3.3 + 0.2 = 5.5 mH

When inductors are connected in series the resultant will be sum of three inductors.

It is same like resistors in series R=r1+r2+r3.

What will the resultant?

If they are connected in parallel?

If they are connected in parallel their resultant is same as that of resistance.

If capacitors are connected in parallel what will be the answer?

Inductance have similar activity of resistor, because are is opposes the current & also inductance opposes the sudden change of current so when the inductors are connected in series, then the result is sum of individual inductors so answer is D.

Resultant inductance will be sum of all inductance if mutual inductance between them are zero.
