the area is going to increase hence the resistance would be1/18 tumes the earlier resistance

Answer:
The length of wire is doubled on itself and so the area get reduced to half.
The resultant resitance will be 4 times.
The process is repeated and therefore the resistance will increase by 4 times. The total resistance will be increased to 16 times.
