Question

how do you test the materials given to you to know whether they are conductors or insulator​

Answer 1

Answer:

Touch the open ends of the two wires to each other to form a circuit and test the bulb. Touch the two open ends of the wire to each material you are testing, one at a time. If the bulb lights up, it is a good conductor. If it doesn't, it is a good insulator.

Materials with high electron mobility (many free electrons) are called conductors, while materials with low electron mobility (few or no free electrons) are called insulators.

Answer 2

Explanation:

Connect one wire between the battery and bulb.

Connect another wire to the other end of the bulb.

Connect the final wire to the other end of the battery.

Touch the open ends of the two wires to each other to form a circuit and test the bulb.

Touch the two open ends of the wire to each material you are testing, one at a time. If the bulb lights up, it is a good conductor. If it doesn’t, it is a good insulator.
