AC Generators AC current pushes electrons back and forth with alternating + and – emf.
{"Image DocumentName": "AC GeneratorsAC current pushes electrons back and forth with alternating + and \u2013 emf.", "Image ImageDescription": "As the coil rotates, it cuts lines of flux first in one direction, then in opposite. EMF varies from + E to - E and has instantaneous value that varies sinusoidally depending on angle of armature with magnetic field. Maximum emf (Emax) generated when coil is perpendicular to magnetic field.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
