Question

Plastics are used to make the handles of screwdrivers and covering of the electrical cables why

Answer 1

because plastic is a good insulator ie a bad conductor of heat and electricity
it ensures the safety of an electrician working with a screw driver and plastic covering on wires also ensures no short circuit.

Answer 2

Answer:

Plastics are used to make the handles of screwdrivers and covering of the electrical cables because it is an insulator and does not allow current to pass through them.

Explanation:

• Both plastic and rubber are insulators.
• Insulators are substances that do not allow electricity to pass through them and thus act as poor electrical conductors.
• They thereby prevent current from passing through them.
• The handles are often constructed of a mix of hard plastic, like cellulose acetate, and rubber, and are ergonomic.
• To increase grip, they can also be wrapped in a soft, non-slip substance like thermoplastic rubber.
• In order to allow electricity to pass through them and protect the electrician from electric shock, the handles of instruments like screwdrivers and pliers that electricians use for repair work typically have a plastic or rubber cover on them.

Thus, plastics are used to make the handles of screwdrivers and covering of the electrical cables because plastic is a poor conductor of electricity and does not allow electricity to pass through it and thus protecting the electrician from electric shock.
