Question

many stereo speaker cables are made of copper wire surrounded by robert electricity travel down the copper portion of the cable while the rubber protects you from being zapped by the electricity which physical property explains the difference in ability of copper and rubber to transmit electricity

Answer 1

Answer: Electrical conductivity

Step-by-step explanation:

Electrical conductivity is the ability of a solution to conduct an electrical current.

Here it is give that current is flowing through the copper wire so this means that copper is good conductor of electricity. It has less resistance and thus it conducts the current easily.

The presence of a rubber coating on copper wire protects us from electric shock as it does not conduct electricity easily and is a poor conductor of electricity. It has high electrical resistance due to which it does not conduct electricity.

Thus it can be said that Electrical conductivity explains the difference in ability of copper and rubber to transmit electricity

Answer 2

Electrical conductivity

Explanation:

Copper is a good conductor of electricity.

Rubber is an insulator — a poor conductor of electricity.
