Question

Distinguish b/w good conductors ,resistor ,insulator .name two good conductor ,two resistors and 2 insulator.

Answer 1

Good conductors are the substances which allow electricity to pass through them without any problem . ex. copper & silver etc.
Resistors are the substances which resist the flow of current through them .ex alloys such as nichrome & tungsten.
whereas insulators are the substance which do not allow electricity to pass through them ex. plastic &wood .

Answer 2

Conductors - which substances which allow the electricity to pass through them, called conductors. Example, copper, silver

Insulators - which substances don't allow the passage of electricity through them, called insulators. Example, rubber, wood

Resistors - they are those electronic components, which have specific never change electrical resistance, called resistors. Example, carbon resistor, metal film resistor..
