Final answer:
Cora wraps the copper wire with plastic coating to reduce energy loss during transmission.
Explanation:
Cora, the electrician, wraps a copper wire with a thick plastic coating most likely to reduce energy loss during transmission. This insulation helps prevent energy dissipation due to electrical resistance in the wire, improving efficiency.
Electrical resistance is a primary source of energy dissipation in electrical systems. Copper wire is commonly used due to its low resistivity compared to other materials like silver.
Increase resistance during transmission would lead to more energy loss, so wrapping the wire with plastic coating aims to reduce resistance during transmission.
