The resistivity of two conductors ‘A’ and ‘B’ are 1.62 x 10−8 Ω m and
5.20 x 10−8 Ω m respectively. Which of them is used in :
(i) Transportation of electricity
(ii) The making of heating coils? Why?

A= transportation of current

B= coil in heater

Explanation:

A that is the one with lower resistance will be used for transportation of electricity...since there loss of current in heat is minimum and so it is effective in transportation of current

B will be used for making heating coils because more the resistance... more current is lost as heat energy and so it will act as good heater
