ibrium is again restored the + chargeis shared between A and C, the — charge between 5 and D, while the differenceof level has decreased. There is the same total number of tubes of induction,but each contains fewer unit cells than before, the energy corresponding tothe decrease having been… … potential when there is equiUbrium. We may say then that the energy-length of the tubes has decreased. During the change some of the electricenergy was converted into magnetic energy in the medium. This might beobserved if sufficiently delicate means were used. If we confine our attention to the…
