Electric Current

The charges in motion is called current. Consider a conductor in cylindrical shape having cross section area A. Inside conductor, electrons are free to move. Their motions are arbitrary. They move randomly inside the conductor. If we consider an imaginary surface S, then number of electrons passing from left to right or from right to …
