Question

how is the Resistance affected if the area is doubled​

Answer 1

$\huge\mathcal{Answer:}$

The cross-sectional area of the wires will affect the amount of resistance. ... When the radius of the wire is doubled it means the area of cross-section is increased by four times. Hence, the resistance of a wire is reduced to one-fourth if its radius is doubled.
