Drift velocity and its relation with current – In this topic we will discuss about drift velocity and how it is related with electric current flowing through a conductor. Drift velocity and its relation with current – As we know a metal contains large numbers of free electrons . At room temperature these electrons moves […]
Electromotive force (EMF) of the cell. In this topic we will discuss about what is Electromotive force (EMF) of the cell and it is different from potential difference . As we know electric current flows through a complete closed circuit ,when there is an source of external force which can bring the ions from low […]
