5.3: Conductors, Insulators, and Charging by Induction

The ground connection is broken before the charged rod is removed, leaving the sphere with an excess charge opposite to that of the rod. Again, an opposite charge is achieved when charging by induction, and the charged rod loses none of its excess charge. Figure (PageIndex{5}): Charging by induction using a ground connection.
