Electrostatics—Part III

Duration: 71 frames

Creator: Society for Visual Education

Format: Filmstrip

Description: Explains that all commercial electrostatic machines are elaborations of the electrophorus, generating electricity by induction rather than by friction. Illustrates the following: Two or more conductors separated by nonconducting material form a condenser; condensers can hold much more powerful charges than can their elements independently; charges attract and bind each other and thus reduce the scattering effect of the mutual repulsion of electrons; charges rapidly escape from points into the air.
