Electricity is a flow of charged particles. These particles originate in
00:00:00
the atom. If you have ever studied the atom you will know that an atom has a
00:00:05
compact center called the nucleus. The nucleus contains two types of particles
00:00:09
protons which have a positive electric charge and neutrons which have no
00:00:15
electric charge. Small charged particles called electrons exist outside of the
00:00:20
nucleus. Electrons have a negative charge and they are attracted to the
00:00:26
positively charged protons. The electrons move in high-speed orbits around the
00:00:31
nucleus, held close to the nucleus by the strong force of attraction from the
00:00:38
protons. You can witness this force by rubbing a balloon on fabric, creating an
00:00:42
imbalance of electrons and protons. Small pieces of paper will stand up and jump
00:00:48
to the negatively charged balloon. Scientists call this static electricity because the charge
00:00:53
doesn't move. It stays on the balloon. Two negatively charged balloons repel one another.
00:01:00
The light charges on each balloon repel. This force can cause electrons to move from one place
00:01:07
to another. When electrons flow between two points, we call this electricity. One of the
00:01:13
One of the most dramatic effects of electricity is a lightning strike.
00:01:20
Electrically charged clouds release their charge in an explosive flash.
00:01:24
A powerful demonstration of electricity.
