If a length of a cylindrical conductor increased by 20% keeping the volume constant.then percentage change in resistance of the conductor is 11×n% the value of n

Question

Arun · Answer

Dear student as volume is constant V1 = V2 A1 * L1 = A2 * L2 L2 / L1 = A 1 / A2 = 1.02 Now R = rho * L /A hence R1 / R2 = L1 *A2/ L2 *A1 R1 / R2 = 1 / 1.02^2 R1 / R2 = 1 / 1.0404 R2 = 1.0404R1
