Discussion
If the resistance of wire is 2 Ω, then conductance of wire is ________.
Answer: D
The conductance is 0.5 mho.
Conductance is the reciprocal of resistance, \(G = 1/R\), measured in mho (siemens).
\[ G = \frac{1}{2\ \Omega} = 0.5\ \text{mho} \]
0.1, 0.3 and 0.4 mho would correspond to resistances of 10, 3.33 and 2.5 Ω.
