By using only two resistances coils-singly, in series or in parallel one should be able to obtain resistance of . The separate resistance of the coil are
View answer and explanation
Correct option: B
Option B (4 and 12) is correct because these resistances can be combined in series (16) and parallel (3), and also used singly (4 and 12).
