Question

Calculate the area of cross section of violent 20000 cm is resistance is 25 ohm and its resistivity is 1.84×10^-6 ohm meter

Answer 1

Answer:

Explanation:

resistance = (resistivity*length)/area

25 = (1.84*10^-6*2)/area

area = (3.68*10^-6)/25

area = (0.736*10^-6)/5

area = 0.1472*10^-6

area = 1.472*10^-7 m^2
