the ______ value indicates the amount of resistance in 1cm of insulation
Thermal
mattalic
The blank space in your question refers to the term "resistivity" or "specific resistance." The resistivity value indicates the amount of resistance in 1cm of insulation material.
To calculate the resistivity of insulation, you need to know two parameters: the resistance and the length. The resistance can be measured using a multimeter or obtained from the insulation material's specifications. The length is the thickness of the insulation in centimeters.
The formula for resistivity (ρ) is:
ρ = Resistance (R) x Length (L)
Once you have the resistivity value, you can use it to determine the resistance of a longer section of insulation, using the formula:
R = (ρ x Length) / Area
Here, "Length" is the length of the insulation in centimeters, and "Area" is the cross-sectional area of the insulation material in square centimeters.
Keep in mind that resistivity values are specific to different insulation materials. It is typically provided by the manufacturer or can be found in engineering handbooks or online resources.
