Distinguish between good conductors, resistors and insulators. Name two good conductors, two resistors and two insulators.
Good conductors:

Resistors:
The substances which have comparatively high resistance than conductors are known as resistors. E.g., Nichrome and Manganin.
Insulators:
The substances which have infinitely high electrical resistance are called insulators. E.g., Rubber, Wood, Plastic.
