Final answer:
The statement about wire code names being only one word is false; multi-word code names can exist. Conductors like wires and light bulbs both have resistance, albeit different levels, and high-voltage wires are held by insulators but are not wrapped in insulating material. Birds on power lines are not electrocuted unless they touch two lines simultaneously, creating a potential difference.
Step-by-step explanation:
The statement about code names for wires being only one word is false. In some contexts, such as military communication and terminology, code names can consist of multiple words. In engineering and electricity, specific conductors may also have multi-word names or codes, although not commonly referred to as such in technical practice.
All conductors indeed have some level of resistance. This implies that while a piece of wire may have less resistance compared to a light bulb, they both impede electrical flow to some degree. Contrary to the high-voltage wires scenario presented, these wires are not wrapped in insulating material; they are held aloft by insulating connectors but are otherwise bare due to the high installation cost of insulators for such long distances and the air itself acts as an insulator.
When a bird sits on a single high-voltage power line, it is not electrocuted because there is no potential difference across its body; the bird is at the same electrical potential as the wire. However, if a bird touches two wires at the same time, it creates a path for current to flow through its body, resulting in electrocution.
