Answer:
The resistance is
Explanation:
Given that,
Diameter of tube = 8.5 mm
Length = 8 cm
Resistivity = 2.5 m
We need to calculate the resistance
The resistance is equal to the product of the resistivity and length divided by the area of cross section .
In mathematical form,
Where, =resistivity
l = length
A = area of cross section
Put the value into the formula
Hence, The resistance is
