Electricity makes the world go round, but what actually is electricity? Scientifically speaking, electricity is a form of energy that is either static (static electricity) or moves from place to place (current electricity). We see this phenomenon naturally occur in nature as lightning. Auroras that appear in the northern skies are related to electricity – where, charged particles from the sun collide with the earth’s magnetic field to produce countless photons.
Today, we have many ways to produce electricity such as hydro-power plants, windmills, solar farms and even nuclear power stations.

What is an electric circuit?
Electric circuit is a path for transmitting electric current. It is used in lamps, motors, computers and many other electronic devices.
What does the ‘Ohm’s Law’ state?
Ohm’s Law states that the current through a conductor is proportional to the voltage across the conductor.
What is nuclear power?
Nuclear power is the controlled use of nuclear energy. Nuclear energy can be released by nuclear reactions in a machine called a nuclear reactor.
