  What is AC supply and DC supply There are mainly two types of Electric supply 1.              AC 2.             DC Electricity is generated in the form of AC(alternating) at generating station/ power station. But what is mean by AC supply ? AC Supply : The quantity which changes its value as well as direction (polarity changes positive to negative) continuously with respect time that is called as AC supply. AC means Alternating Current .   Polarity of AC supply is continuously changes. AC supply can produced magnetic fluxes whenever current flowing through conductor. This nature of AC supply makes it very very useful. AC supply is further converted into DC by using filters in order to used for various electronics and other application. AC can not be stored in batteries. AC supply have frequency of 50 Hertz. The machines which are operate on AC supply that   machine are called as AC machin...

What is electricity  ? Electricity is nothing but energy. We know that energy neither be created nor be destroyed only it can converted into one form to other form . Before invasion of electricity there is only mechanical energy present. therefore all work are done by using mechanical machines but efficiency of mechanical machines is too low. Electricity was discovered by Benjamin Franklin in 1752. After that Michael  Faraday discovered the device that convert Mechanical energy into Electrical energy that is called generator this is one of the great invasion of faraday. before discovery of electricity work was done by mechanical energy e.g. steam engine, fuel engine etc. But know electrical devices replacing mechanical devices. Main parameters of electrical  system are current, voltage and power. Electric Charge :  In easy word, we know that every element made up of atom and atom contains protons & electrons. when electric supply given to any wire or conductor el...
