Resistivity of Conductor-   Before you go through this article, make sure that you have gone through the previous article on Resistance of Conductor.   We know- The resistance of a conductor of length L and area of cross-section A is given by-     If L = 1 unit and A = 1 unit, […]

Mechanism of Current Flow In A Conductor-   Before you go through this article, make sure that you have gone through the previous article on Mechanism of Current Flow In A Conductor.   We have learnt- When a potential difference is applied across the ends of a conductor, an electric field is created inside it. […]

Electric Current-   Before you go through this article, make sure that you have gone through the previous articles on Electric Current & Drift Velocity.   We have learnt- Electric current is the flow of electric charges (free electrons) through a conductor in a preferred direction. Drift velocity is the average uniform velocity with which […]

Electric Current-   Before you go through this article, make sure that you have gone through the previous article on Basics of Electric Current.   We have learnt- When electric charges (free electrons) flow through a conductor in a preferred direction, it constitutes an electric current. The amount of charge flowing through the area per […]

Electricity-   The branch of physics which deals with the study of electric charges is called as Electricity.   There are two branches of electricity-     1. Static Electricity-   The branch of physics which deals with the study of electric charges at rest is called as static electricity also called as electrostatics.   […]
