Question

what happens to length when cross sectional area is doubled when finding resistance ​

Answer 1

Answer:

Resistance is directly proportional to area and inversely proportional to length. Hence if we increase resistance we get increased area and decreased length and vice - versa...

Answer 2

Answer:

As per basic equation of resistance, value of resistance is directly proportional to length & inversely proportional to area. Hence if both length & cross-sectional area are doubled the value of resistance will remain the same as that of earlier value.
