Question

1. why then do you think that wires, like your phone charger, have materials like metal on the inside and materials like rubber on the outside?

Explanation:

Metal is a good conductor of electricity, allowing the flow of electric current through the wire for charging. Rubber is an insulator, preventing electric current from leaking out and protecting users from electric shocks.
