When two coupled coils of equal self-inductance are connected series in one way, the net inductance is 12 mH and when they are connected in the other way, the net inductance is 4 mH. The maximum value of inductance when they are connected in parallel in a suitable way is:
1
2 mH
2
3 mH
3
4 mH
4
6 mH
