Question

What are the two methods of testing to check whether a material is an insulator or a conductor?

Answer 1

Explanation:

Home delivery is the bringing of items to the customer's home rather than the customer taking or collecting them from the store. In the first cash-and-carry stores, items were sold only for cash; no credit was extended, and no expensive home deliveries were provided.

Answer 2

Answer:

Try it this way:

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.
