Expert Answer:

In everyday life we find bulbs in lampshades or fluorescent tubes all around us in houses, offices, restaurants etc. You must have  wondered  what  causes  the  bulb  or  the  tube  to light up ? " Actually  they need the electricity to light up. Electricity passes through  wires that are  attached to them and it makes the bulbs and tubes glow.
 

 

WHAT IS ELECTRICITY?

All things are made up of very thin particles called atoms. Everything from metals, wood, glass, water and gases are made of atoms.

We cannot see atoms because they are very, very small. However, scientists have found out that even atoms are made up of  smaller particles. One of the many types  of particles in an atom is the electron.

We get electric current because of the movement of the electrons. So, current is the flow of electrons. One might imagine electrons  traveling from  one end of the wire to the other end and making a continuous flow, just like the flow of water in a pipe ( though the two  are not exactly identical ).

 

 

HOW ELECTRICITY TRAVELS

 
Electricity travels along a path. If the path is blocked,    then electricity cannot keep flowing. The whole path along which electricity  travels is known  as a circuit. A broken path is known as an 'Open Circuit' and the electricity  can not flow in an open  circuit. An unbroken path is known as a 'Closed  Circuit' and the electricity can flow.
