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