One common problem all the electronics beginners have to face,

Hello friend, how are you, is everything going well? Do you have any problem? Share with us,
Actually problem is everywhere, in personal life, in professional life. Every day we have to face many problems, but we should not take our foot behind, we have to fight with it, we have to find the solution,
One common problem all the electronics beginners have to face, that is we make electronics circuits whose out put power can drive a few mili-watt load, like a LED, but if we have to drive a load of 100 watt(any home appliances) load, then how it is possible?
 Here is the solution- just use a magnetic relay.
What is a relay?
 Relay is an electro-magnetic switching device, used to interface high voltage load with low voltage control circuit.
How a relay works-
Relay is normally a 5 pin device, among them one is normally open (NO)  pin and other is normally closed (NC) pin.

Look at the picture, you will easily understand how it works.
