VOLTAGE CONCEPT

Voltage:

                     The difference of charges b/w two point's called voltage or potential difference .it is also called emf.

Concept :

                     It is actually push of chargers you can easily understand from fig which given below :

 Explain:

               It's mean how much charges difference between two terminals or point's.

let suppose ; At point A charge is 5 coulomb and at point B is 8 coulomb than their difference is 3 which we says voltage or potential mean 3 volt's .

                              V:(VOLTAGE )

Formula:

                         V=IR          V VOLTAGE ,I CURRENT , R RESISTANCE or v= delta E/r      E is a potential gradient is is distance

UNIT: 

          It is unit of potential difference  .
