if the lengths of two wires are same and the area of cross sections is 4:7 then what will be the r..

Answer / Ramesh Singh Yadav

Since the resistance (R) of a wire depends on its length (L) and cross-sectional area (A), we have the formula R = rho * L / A, where rho is the resistivity of the material. Given that the lengths are the same, any difference in current will be due to differences in the cross-sectional areas.nSince the area ratio is 4:7 for the two wires, the current (I) passing through them will have a reciprocal area ratio, which means I1 / I2 = 7/4. Keep in mind that this assumes a constant voltage and resistivity of the materials.
