Resistance will be 4 times because as the length gets double(2 l ) , area will becomes half(A/2) then send the downward 2 to upward , u will get 4 times the original one......Hope this help

Resistance becomes double because RESISTANCE is directly proportional to Length. Here the length is double not diameter which is diameter of thickness doubled

1/4times

Length is double then resistance become double.

Resistance become double because resistance is directly proprotional to length of a given wire...

Sia ? 6 years, 3 months ago

Because the thickness of a wire is usually represented by its diameter. Thus when the diameter of a wire is doubled (made 2 times), its resistance becomes one-fourth (1/4).
