Question

3. Differentiate between conductors and insulators .​

Answer 1

Answer:

Conductors Insulators

They allow the current of electricity to flow through them. They do not allow the current of electricity to flow through them.

They have large numbers of free electrons. They have a small number of free electrons

Answer 2

Differentiate between conductors and insulators.

Explanation:

• Substances through which electricity can flow are called conductors, those substances through which electricity cannot flow are called insulators.
• Conductors have low electrical resistances, Insulators have infinitely high resistance.
• Conductors have large number of free electrons, Insulators do not have free electrons.
• Conductors include metals e.g. silver, copper, aluminium, Insulators generally include non metals  e.g. wood rubber, plastic.
