Give reasons for the following.

Why wires cannot be drawn from materials such as stone or wood?

Reason:

Only a small amount of electricity passes through stone and wood. Hence, wires cannot be drawn from them.
Stone and wood are hard, so wires cannot be drawn from them.
Since stone and wood are non-conductors of electricity, wires cannot be drawn from them.
