Coil such that current is induced in it by passing a current through the primary coil.
1The current passes, by induction, from the primary to the secondary coil.
2The spark from secondary coil of the inductorium passed from the platinum tip, piercing the paper.
3The secondary coil should be wound with single covered wire, preferably silk-covered, although cotton will do.
4The low voltage secondary coil which heats the filament develops 10.5 volts.
5TRANSFORMER.- Aprimaryand a secondary coil for stepping up or down a primary alternating or oscillating current.
6The spark from the secondary coil of an inductorium was delivered from a wire near the tip of the fork.
7The intermittent, or rather alternating, currents from the secondary coil are often applied to the body in certain nervous disorders.
8The voltage of the grid of the modulator tube is varied by the secondary coil of the induction coil or microphone transformer, above described.
9The outer or secondary coil S C is of long thin wire terminating in two discharging points D1 D2.
