Question

what happens to resistance of a conductor if area of cross section is doubled​

Answer 1

Answer:

its electromagnetic force increases and repulsion also

Answer 2

Answer:

R =rho × length/area

R is inversely proportional to area of cross section

R1/R2=A2/A1

R/R2=2A/A

R2=R/2

SO THE THE RESISTANCE BECOMES HALF OF THE ORIGINAL
