Question

Electric wires are always covered with insulators to make them

• A. colourful
• B. safe
• C. thick

Answer 1

The correct option is B

safe

Conductors and Insulators:

1. Substances that allow the electric current to pass through them are known as conductors.
2. Some examples of conductors are metals, iron, copper, etc.
3. Substances that do not allow the electric current to pass through them are known as insulators.
4. Some examples of insulators are plastic, wood, etc.

Hence, electric wires are always covered with insulators to make them safe, so that we don't receive any electric shock.

Thus, option B is correct.
