Insulation Resistance of Single Core Cable
Insulation resistance is the resistance offered by the insulating material between two conductors. The insulation resistance of a single core cable is given as 200 MW/km.
Calculation of Insulation Resistance for 5km length
To calculate the insulation resistance for a 5km length of cable, we can use the following formula:
Insulation Resistance = (Resistance per unit length) x Length
Substituting the given values, we get:
Insulation Resistance = 200 MW/km x 5 km
Insulation Resistance = 1000 MW
Therefore, the insulation resistance for a 5km length of cable is 1000 MW.
Answer and Explanation
The correct answer to the question is option A, which is 40 MW. However, the given explanation is incorrect as it calculates the insulation resistance for a 5km length of cable as 1000 MW, which is incorrect.
The correct calculation for insulation resistance for a 5km length of cable is 200 MW/km x 5 km = 1000 MW. Therefore, the correct answer is option A, which is 40 MW/km.
In conclusion, the insulation resistance of a single core cable is 200 MW/km, and the insulation resistance for a 5km length of cable is 1000 MW.

The correct answer to the question is option A, which is 40 MW. However, the given explanation is incorrect as it calculates the insulation resistance for a 5km length of cable as 1000 MW, which is incorrect.
The correct calculation for insulation resistance for a 5km length of cable is 200 MW/km x 5 km = 1000 MW. Therefore, the correct answer is option A, which is 40 MW/km.
In conclusion, the insulation resistance of a single core cable is 200 MW/km, and the insulation resistance for a 5km length of cable is 1000 MW.
