 1.Step-up Transformer  2.Step-down Transformer 

So the image shown here is of a Transformer, basically Transformer are of many types and here it is 3 phase Distribution Transformer which Pole mounted.

This is Full require material I wrote during my notes. So you can go through it.I hope you will get what we have done to obtain the Formula.

You must have seen a plug or a socket in which  one pin or point is big and thick as compared to other two pins  which are equal to each other.  So why is that soo ? Here is the Answer to your question So there are basically 3 major reason behind this and lets have a look over these. 1 . Plug is inserted Properly-  The plug consists 3 pin so if all pins will be equal then someone might put earth pin in the phase or neutral due to which connection will get wrong and if Earth pin is connected to phase then the current will flow in the machine outer body which can cause major damage to one touching it. 2. Earth pin will enter first and exits last-  As we know earth pin is used to protect us from any leakage current in any machine's conductive body. So we must put earth pin before Phase to be safe from any fault current occurring later,and due to this only Earth pin is taken out at last so that if any fault currrnt is their then firstly supply is disconn...

Soo You have seen Lightning during bad weather or in Rainy days. Do you also heard about several myths about lightning from your parents or from your grandparents. Lets have a look to them and check that weather they are myth or not.     So lets begin; 1. Lightning never strikes twice at the same place. " So it is completely wrong,Lightning can strike anywhere it want their is no such place where it will strike or not." 2.  Lightning strikes only at tall buildings. So have a look to the image below,This is the tallest building and it face about 25 Lightning strikes in a year. Soo its right but you may have also heard that some Village also faces Strike, how come their are no tall building. "Lightning does not see height it strikes where it wants." 3. If you're stuck somewhere then being under tree is best. So it is not correct even it is very dangerous to ones life. "Trees have positive charge which help in lightning and if tree get ...

So You must have this question in your mind that Does Lightning and sound is produced at the same time or not because Lightning is seen Before we heard Thunder Sound . So as shown in above image We can understand that lightning and sound have a lot a difference between their respective speed and the Winner is light as it has more speed than of Sound and it is the answer to your question.  Lightning is produced because negative charge collides with positive charge in clouds or sometimes with Ground which have positive charge. One more thing is that they both are produced at the same time. The sound is produced because the light have a lot of heat which replaces the cool air in the atmosphere and thus Thunder sound is produced... So I hope you got the answer to your question do tell your friend about the reason behind this...
