We know that,
Circumference of the wire = 2πr
Thus, resistance per unit volume of the wire = 4/2πr = 2/πr
So, resistance of the specimen = 2/πr × 2r = 4/π
And resistance of the halves of the wire = 2/πr × πr = 2
Now, Equivalent resistance will be decided as 4/(4+π) as 4/π,2,2 are in parallel combination.
The diameter of the field of view decreases when changing from low to high power magnification. This is because higher magnification zooms in closer on the specimen, limiting the area of the specimen that can be seen at one time.
The amount of specimen visible on a microscope is referred to as the field of view. This refers to the diameter of the circular area that is visible when looking through the microscope. The field of view may vary depending on the magnification level of the microscope lens.
A particular specimen could be described by its size, density, color, resistance to fracture, texture, and mineralogy.
if we know resistivity of copper i.e is very small (1.68×10−8)transposing the definition to make resistance the subject (Pouillet's law):R is the electrical resistance of a uniform specimen of the material (measured in ohms, Ω) is the length of the piece of material (measured in metres, m)A is the cross-sectional area of the specimen (measured in square metres, m²).

To calculate the compressive stress in the concrete test specimen, we first need to determine the original cross-sectional area of the specimen. The original cross-sectional area can be calculated using the formula for the area of a circle: A = πr^2, where r is the radius of the specimen (6 in diameter means a radius of 3 in). Once we have the original cross-sectional area, we can calculate the compressive stress using the formula stress = force/area. Given the total deformation under load (0.015) and the original cross-sectional area, we can calculate the compressive stress in the concrete test specimen.
