    Examples of Conductors

                      Some of the examples of Conductors are:

                         • Metal like copper, aluminium,
                         or iron.

                         • The wires in your house are

                         made of metal because they
                         let electricity travel through

                         them.

                      What is an Insulator?

                      An insulator is something that
                      stops electricity from passing through it. This makes it safe to touch and

                      protects us from getting hurt by electricity.

                      Examples of Insulators

                      Some of the examples of Insulators are:

                         • Plastic, rubber, and wood.

                         • The outside of electrical wires is made of plastic so that we don’t get

                         an electric shock.

                      Battery

                      A  battery  is  a  small  power  source  that  gives
                      energy to things like toys, flashlights, and remote

                      controls.  It  stores  electricity  inside  and  helps
                      devices work when they are connected to it.

                      What is Battery’s Polarity?

                      Polarity means that a battery has two sides or ends:

                      1. Positive (+) side

                      2. Negative (-) side

                      These sides are called terminals. The positive terminal is marked with a

                      plus sign (+) and the negative terminal is marked with a minus sign (-).
