Which of the following will result in the highest conductance? large cross-sectional area, short pipe
small cross-sectional area, long pipe
small cross-sectional area, short pipe
large cross-sectional area, long pipe

The highest conductance results from;

Large cross-sectional area, short pipe

Explanation:

The conductance, G, of a material is a measure of the rate or ease of electricity conduction of the material

Where;

I = The current

V = The voltage (Potential difference)

R = The resistance

A = The cross-sectional area of the conductor

L = The length of the conductor

ρ = The resistivity of the conductor

Therefore, "G" is directly proportional to "A"  ang "G" is inversely proportional to "l" from which we have that as the cross-sectional area increases the conductance increases and as the length of the pipe decreases the conductance increases.

The highest conductance is given by a large cross-sectional area and a short pipe.

b would be the answer

none, its a machine
