Question

A switch is something that is used in a circuit to allow the flow of current by completing the circuit or to stop the flow of current by creating a gap in it.

Which of the following is an ESSENTIAL characteristic of the switch in order to allow the electricity to flow through the circuit?
1 It must be made only of metal.
2 It must be made only of plastic.
3 It can be made of any material, but must be flexible like a wire.
4 It can be made of any material, but must be a good conductor of electricity.

​

Answer 1

Answer:

2 is the answer

Explanation:

because circut bever comes on plastic

Answer 2

Answer:

It must be made only of plastic.

Explanation:

• Plastic is an insulator.
• So if it is made of metal it may give us a shock because electricity is passing.
• So it should not be a conductor of electricity
• It does not need to be like a flexible wire also
• So the answer is it must be made only of plastic.
