B. Large cross-sectional area, long pipe
C. Small cross-sectional area, short pipe
D. Small cross-sectional area, long pipe

Respuesta :

Answer:small cross-section area,long pipe

Explanation:

Conductance is a measure of how easily the current can flow through a electrical component.

It is the inverse of resistance.

Conductance is given by [tex]\frac{cl}{a}[/tex]

where [tex]c[/tex] is conductivity(constant for a component),[tex]l[/tex] is the length of component parallel to the flow and [tex]a[/tex] is the area of cross-section of the component perpendicular to the flow.

So,conductivity increases with increase in [tex]l[/tex] and decreases with increase in [tex]a.[/tex]

So,small cross-sectional area and long pipe has high conductance.
