When the area of cross-section of a conductor is doubled, its resistance becomes:

The length and area of cross-section of a conductor are doubled, its resistance is

If the area of cross-section of a resistance wire is halved, then its resistance becomes:

When the length and area of cross-section both are doubled, then its resistance

When the length and area of cross-section both are doubled, then its resistance

When the length and area of cross-section both are doubled, then its resistance

When the diameter of a wire is doubled, its resistance becomes:

If area of cross-section of a metalic wire becomes n times, its resistance becomes

When length of a metal wire is doubled and area of cross-section is reduced to half, then its resistance becomes
