Answer 1:
A good rule of thumb is that any metal object
is a conductor. So in a house, you could find
many conductors in a kitchen, for example pots
and pans, forks, knives, and spoons. The metal
coins in your wallet or purse are also
conductors. Other metal conductors are jewelry,
tools, wires, and pens. Can you find other
conductors in your house?
If you find a metal object that does not
conduct, it is probably because it has some type
of plastic or oxide coating on it. These types
of coatings prevent electricity from entering
the metal.
There are also few types of materials you
could find in your house that conduct
electricity that are not metals.
One material is pencil graphite. Graphite is
made of carbon, which is not a metal, but it can
also conduct.
The water in your house also conducts
electricity. Perfectly pure, distilled water
does not conduct, but most water is not
perfectly pure. The water in your house has ions
dissolved in it. Ions are
As you know, there are many things in a house
that are not conductors. Things made of wood,
plastic, or fabric, are insulators. Insulators
do not conduct electricity – they insulate from
electrical current.
