Ex1: In nature, as flashes of lightning during a
rainstorm.
Ex2: Hold the brush next to your head. This happens
because the brush and your hair have got different
electric charges
Where can we see
electricity ?
3.
Everything in nature is made of
ATOMS, which contain particles
called protons amd electrons.
Protons have got a positive electric
charge , and electrons have got a
negative electric charge.
6.
Electrically neutral: equal number of protons and
electrons
Electrically charged : unequal number of protons
and electrons
When there are more protons than electrons in a object,
we say that it is positively charged. But if there are
more electrons tha protons , we say that the object is
negatively charged
Neutral or charged
