The electrical copper wires are coated in rubber or plastic to ensure that no current is diverted away from where it is intended to go. As rubber and plastics make very good insulators, as well as being cheap, easy to apply and flexible, it ensures that the electricity wont be conducted away from the circuit when in close proximity to another wire or any other conducting surface (or someones hands).

What is it called when copper is pulled into thin wires?
When copper is pulled into thin wires, it is called copper wire drawing. This process involves passing the copper through a series of decreasing diameter dies to gradually reduce its diameter and form a thin wire.
In what proportion copper is used to make electric wires?
Copper is the primary metal used to make electric wires due to its high electrical conductivity. Copper wires are typically made of 99.9% pure copper to ensure efficient transmission of electricity.
What of all these materials is most elastic steel copper wood rubber?
Rubber is the most elastic material among steel, copper, wood, and rubber. Rubber can stretch significantly before breaking, making it highly elastic compared to the other materials listed.
Why copper rod is covered with insulating material in Searle's apparatus?
The copper rod in Searle's apparatus is covered with insulating material to prevent heat transfer between the rod and the surrounding environment. This helps to maintain a constant temperature along the length of the rod, allowing for accurate measurements of thermal conductivity.
Why is copper commonly use to make electric wires?
Copper is commonly used to make electric wires because it is an excellent conductor of electricity, allowing for the efficient transfer of electricity through the wires. Copper is also highly conductive and ductile, making it easy to shape into wires for various electrical applications. Additionally, copper has good corrosion resistance, ensuring the longevity and durability of the wires.
