Final answer:
Rubber and wood are insulators, not good conductors of electricity.
Step-by-step explanation:
Rubber and wood are not good conductors of electricity. They are actually insulators which means they do not allow electricity to pass through easily.
In contrast, materials like metals such as copper and aluminum are good conductors of electricity because they contain freely moving electrons that can carry electrical charge.
It is important to note the difference between conductors and insulators when considering the flow of electricity.
