WebThe circuit above shows a simple DC triggered triac power switching circuit. With switch SW1 open, no current flows into the Gate of the triac and the lamp is therefore “OFF”. When SW1 is closed, Gate current is applied to … WebMay 8, 2000 · In a generator, you reverse the process. You move a magnet past the armature to create electric current in the coil. A magneto consists of five parts: An armature. In the above magneto, the armature is shaped like a capital "U". The two ends of the U point toward the flywheel. A primary coil of perhaps 200 turns of thick wire wrapped …
