Question

$ 2,4 $ and $ 6 \mathrm{~S} $ are the conductances of three conductors. When they are joined in parallel, their equivalent conductance will be, $ 12 \mathrm{~S} $, $ \frac{1}{12} \mathrm{~S} $, $ \frac{12}{11} \mathrm{~S} $, $ \frac{11}{12} \mathrm{~S} $

We know that R = 1 S R 1 = 1 2 Ω , R 2 = 1 4 Ω , R 3 = 1 6 Ω In parallel combination, the equivalent resistance is given by 1 R p = 1 R 1 + 1 R 2 + 1 R 3 = 2 + 4 + 6 = 12 Ω Hence, the equivalent conductance is G = 1 R p = 12 S
