Question
The resistivity of insulators is typically in the range:
Explanation
Insulators have high resistivity ( 10¹Ⱐto 10¹â¹Î© m ) or low conductivity ( 10â»Â¹Â¹ to 10â»Â¹â¹ S m^{-1 ), preventing significant current flow. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.
