Detailed explanation-1: -Good conductors like copper, aluminium, etc., offer low resistance to the flow of current. This is because they contain a large number of free electrons.
Detailed explanation-2: -The Resistivity of Various Materials Good conductors have less resistivity. Insulators have a high resistivity.
Detailed explanation-3: -Conductors: Materials that offer very little resistance where electrons can move easily. Examples: silver, copper, gold and aluminum. Insulators: Materials that present high resistance and restrict the flow of electrons.
Detailed explanation-4: -The more conductive something is, the less resistance it will have.
Detailed explanation-5: -Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them.
