Question

which sequence lists types of materials in order from least conductive to most conductive?
o superconductor → conductor → semiconductor → insulator
o insulator → conductor → semiconductor → superconductor
o conductor → superconductor → semiconductor → insulator
o insulator → semiconductor → conductor → superconductor

Explanation:

Insulators have the lowest electrical conductivity (block current flow), semiconductors have moderate conductivity (can be adjusted), conductors have high conductivity (allow easy current flow), and superconductors have zero electrical resistance (highest conductivity). This order from least to most conductive is insulator → semiconductor → conductor → superconductor.

Answer:

insulator → semiconductor → conductor → superconductor
