Scott was watching the electrician install a new light fixture. scott noticed that when he was finished, he carefully wrapped some wires with plastic caps and black plastic tape. select the best explanation of why the electrician would wrap electrical wires with plastic products. (1 point) a. the electrical wires are made of metal, which conducts electricity. in order to make the wiring safe, he would wrap the exposed wire with plastic materials, which are good insulators. this keeps the flow of electricity contained to the light fixture and wiring. b. the electrical wires are made of metal, which is a good insulator. the plastic caps and tape are good conductors. this combination will limit the flow of electricity to only the light, the wires, and the home circuit. it will not allow any electricity to flow elsewhere. c. the electrical wiring is made of metal, a conductor. in order for the electrical current to flow properly, the electrician would need to place plastic materials, which are good conductors, at the ends of the wires. d. it is important to practice good safety measures when dealing with electricity. the plastic caps and tape are good conductors and will protect anyone who comes in contact with the wires from being shocked.
