Compute the voltage drop....?

Compute the voltage drop along a 24 m length of household no. 14 copper wire (used in 15 A circuits). The wire has diameter 1.628 mm and carries a 10 A current.

idk what no 14. copper wire is, and also help me solve this problem.

    1.628 mm diameter copper wire has gauge no 16area of cross section 2.0755 mm^2

    and has a resistance of 0.00831 Ω / m

    24 m has a resistance of 24 *0.00831 = 0.19944 Ω

    P.D = current *resistance = 10*0.19944 =1.9944 ~ 2 V

    =================

    14 copper wire has diameter 2.032 mm diameter and has 3.2429 mm^2 area of cross section and has a resistance of 0.00532 Ω / m

    24 m has a resistance of 24 *0.00532 = 0.12768Ω

    P.D = 1.2768 ~ n1.3 V
