Question

The resistance of 120 meters of wire is 16Ω. What is the conductance of the wire from one end
to the middle?

Answer 1

Conductance of a wire is inversely related to its resistance.

Resistance = 16 ohms

Conductance $= \frac{1}{16}\; ohms = 0.0625 \; mhos$

Per unit length conductance $= \frac{1}{16 \times 120} = 0.0005208 \; mho/m$

The conductance of the wire from one end to the middle $= 0.0005208 \times \frac{120}{2}$

$= 0.0005208 \times 60 = 0.03125 \;mhos$
