D26. Electric Field Inside a Hollow Conductor

ELECTROSTATICS - Electric Fields

---

(By induction) A conducting gallon paint can with an orifice in the top is charged with the electrophorus. The lecturer attempts to charge two small conducting spheres by induction inside the container. Because of the absence of an electric field inside the container, the spheres get no charge. If the same process is repeated outside the container, the spheres become charged oppositely. This is shown with an electroscope. This demonstration can also be done with a hollow sphere.
