The top of the atmosphere is at about 400 kV with respect to the surface of the earth, corresponding to an electric field that decreases with altitude. Near the surface of the earth, the field is about 100 Vm−1. Why then do we not get an electric shock as we step out of our house into the open? (Assume the house to be a steel cage so there is no field inside!)
What is the geometrical shape of equipotential surfaces due to a single isolated charge?
Define equipotential surface.
Statement - 1: For practical purpose, the earth is used as a reference at zero potential in electrical circuits.
