Calculation of Insulation Resistance of 8m Long Cable Sample
Given:
Insulation resistance of 2m long cable sample = 10MΩ
To find:
Insulation resistance of 8m long cable sample
Solution:
To calculate the insulation resistance of a longer cable sample, we can use the following formula:
Insulation resistance = (Length of cable sample being tested / Length of reference cable sample) x Insulation resistance of reference cable sample
Using the above formula, we get:
Insulation resistance of 8m long cable sample = (8/2) x 10MΩ
Insulation resistance of 8m long cable sample = 40MΩ
Therefore, the correct option is (b) 2.5MΩ.
Explanation:
In the given question, we are given the insulation resistance of a 2m long cable sample. We need to calculate the insulation resistance of an 8m long cable sample using the given information.
To do this, we use the formula mentioned above. We know that the insulation resistance of the reference cable sample (i.e., the 2m long cable sample) is 10MΩ. We also know the length of the cable sample being tested (i.e., 8m) and the length of the reference cable sample (i.e., 2m).
Using the formula, we can calculate the insulation resistance of the 8m long cable sample, which comes out to be 40MΩ. Therefore, option (b) 2.5MΩ is incorrect, and the correct answer is option (a) 40MΩ.
