Question

Distinguish between good conductors, resistors and insulators. Name two good conductors, two resistance and two insulators.

Answer 1

Substances that conduct electricity easily and offer very low resistance (opposition) to the flow of current are called good conductors. Examples: copper, silver

A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit. Resistors have comparatively high electrical resistance. Examples: constanan, nichrome

The substances that have infinitely high electrical resistance are called insulators. Examples: wood, rubber
