Question

Calculate conductance of a conduit the cross-sectional area of which is 1.5 cm2 and the length of which is 9.5 cm, given that its conductivity is 0.65 ohm-1 cm-1.

0.15 ohm-1
0.10 ohm-1
1.2 ohm-1
7.5 ohm-1

Answer 1

The conductance of the conduit is 1.54 ohm-1 cm-1.

Step-by-step explanation:

Conductance is the reciprocal of resistance and is calculated using the formula G = 1/R, where G is the conductance and R is the resistance. In this case, we are given the conductivity of the conduit, which is the reciprocal of resistivity. The resistivity of the conduit can be found using the formula ρ = 1/σ, where ρ is the resistivity and σ is the conductivity. The resistivity of the conduit is given as 0.65 ohm-1 cm-1, so we can calculate the conductance as G = 1/0.65 ohm-1 cm-1 = 1.54 ohm-1 cm-1. Therefore, the conductance of the conduit is 1.54 ohm-1 cm-1.
