Copper wire is a good electrical conductor because

  • A Some electrons in the metal can move easily within the wire
  • B The particles of copper can move easily within the wire
  • C It is encased in plastic
  • D Copper already contains electricity
That's Correct!
It's Wrong!

Copper wire is a good electrical conductor because some electrons in the metal can move easily within the wire. In metals, such as copper, the outermost electrons of the atoms are loosely bound and can move freely. When a voltage is applied, these free electrons can easily flow through the wire, carrying electric current. This property of copper allows it to efficiently transmit electricity, making it a commonly used material in electrical wiring.
