\mathrm{3,4,12 }\,\mathrm{and }\,\mathrm{16 }\,\mathrm{ohm}

. The separate resistance of the coil are

View answer and explanation

Correct option: B

\begin{array}{llllllllllllllllllll} {\mathrm{4 }\,\mathrm{and}\,\mathrm{ 12}} \end{array}

Option B (4 and 12) is correct because with resistances of 4 and 12 ohms, we can obtain 3 ohms (parallel), 4 ohms (single), 12 ohms (single), and 16 ohms (series).
