View Answer 13 -20 Explanation:- Answer : A Discuss it below : Shanmugapriya Karthikeyan Said on 2023-10-13 23:16:58 Given : V = 1V, I = 1 µA. [µ = 10^-6] Resistance = V/I = 1/(110^-6) . Conductance = 1/Resistance = 1 / (1/110^-6) = 10⁶mho. Resistance is inversely proportional to the conductance. !!
