Explanation:
Here current is flowing through the copper wire so this shows that copper is good conductor of electricity.
It is having less resistance as it conducts the current easily
Now a rubber coating on it will protect us from electric shock
So this property shows that rubber is a bad conductor of electricity
It is having large electrical resistance due to which it will conduct no current
Rubber : - No transmittance of electricity
copper :- good transmittance of electricity
