This Smaller generators are sometimes self-excited, which means the field coils are powered by the current produced by the generator itself. The field coils are connected in series or parallel with the armature winding. When the generator first starts to turn, the small amount of remanent magnetism present in the iron core provides a magnetic field to get it started, generating a small current in the armature. This flows through the field coils, creating a larger magnetic field which generates a larger armature current. This bootstrap process continues until the magnetic field in the core levels off due to saturation and the generator reaches a steady state power output. -874 Other electronic items in a household draw their power from the mains using a wall wart. The steady state power consumed by each component is pretty low, and in many cases likeprinters, scanners etc., they dont work continuously.
