But it is perhaps of i^reater interest to note, that the lampincreases in brightness when the plate is disconnected (Fig. 179a).In this case all the energy the primary receives is now sunk intoit, like the charge of a battery in an (»cean cable, but most of thatenertV is recovered throuirli the seconil;u-\- lunl used to lisrht thelamp. The current traversing the primary is strf)ngest at the endA which is comiected to the terminal Ti oi the induction coil, and.
