According to ohm’s law the current (I) flowing through a conductor is directly proportional to the potential difference (V) across the ends of the conductor, provided temperature of the conductor is kept constant, i.e. I V or V...

The reason of current flow in a metallic wire is the flow of free electrons present in it. When a metallic wire is not connected to a source of electricity the electrons present in it are free to move in all directions. As a result, there is no net flow of current in...
