Question

Which of the following will result in the highest conductance ?

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

Answer 1

Answer:small cross-section area,long pipe

Step-by-step 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
`(cl)/(a)`

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

So,conductivity increases with increase in
`l` and decreases with increase in
`a.`

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