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

If the diameter of a resistance wire is halved, then 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

When the area of cross-section of a conductor is doubled, 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

Resistance of a wire of circular cross-section is 2 Omega . If both the length and radius of cross-section of the wire be halved, then what will be the resistance of the wire ?
