Question

Two wires of same material and same length have 'R' resistance r1 and r2 respectively.compare thier 'R' resistance

Answer 1

u know that resistance is inversely prportional to area of cross section

so, R = 1/A X p (where p is resistivity)

now R = 1/A because resistivity is constant

R = 1/1 = 1

and R = 1/2 =0.5

now comparing these resistance is more in wire having less raddi 

i hope u assure it its correct thumbs up
