Detailed Solution

The given statement is false.
The resistivity of rubber gloves is very high, so they are used as an insulator by the electrician. The resistivity of the conductor is very lower, whereas the resistivity of the insulator is very high. The resistivity of a substance is virtue due to which it resists the flow of current. Metals are good conductors of electricity, and rubber is a bad conductor of resistivity. The resistivity of semiconductors like silicon and germanium is in between those of conductors and insulators. The resistivity of the insulator is very high. The resistivity does not depend on the length or thickness of the substance. It depends on the nature of the substance and temperature.
The correct statement would be that the resistivity of the conductor is lesser than an insulator.
