Resistance of a conductor of length l and area of cross-section A is R. If its length is doubled and area of cross-section is halved, then find its new resistance.

Resistivity of a conductor of length l and cross - section A is rho . If its length is doubled and area of cross-section is halved, then its new resistivity will be .

If the length of a wire is doubled and cross-sectional area is halved, what happens to the 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 length and area of cross-section both are doubled, then its resistance

If the length of a wire is doubled and its cross-section is also doubled, then its resistance will

Write in the form of a formula a relationship between resistance and resistivity of an ohmic conductor. A wire of length ‘l’ and resistance ‘R’ is stretched so that it’s length is doubled and area of cross section is halved. How will its resistance change?
