Question

By using only two resistance coils singly, in series or in parallel one should be able to obtain resistances of 3 , 4 , 12 and 16 Ω . The separate resistances of the coil are, 3 and 4, 4 and 12, 12 and 16, 16 and 3

If we take R ⁡ 1 = 4 Ω , R 2 = 12 Ω then in series resistance R = R 1 + R 2 = 4 + 1 2 = 16 Ω In parallel, resistance R ⁡ = 4 × 12 4 + 12 = 3 Ω So R ⁡ 1 = 4 Ω , R 2 ⁡ = 12 Ω
