Question

how can we decide whether an object is a good conductor or weak conductor​

Answer 1

in a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. ... Most atoms hold on to their electrons tightly and are insulators.

Answer 2

weak conductor object not heavy this is not good condition
