How does an AC generator start initially , as there is no movement in the armature |
| Answer» In electrical engineering, an\xa0armature\xa0is the component of an\xa0electric\xa0machine which carries\xa0alternating current. The\xa0armature\xa0must carry current, so it is always a conductor or a conductive coil, oriented normal to both the field and to the direction of motion, torque (rotating machine), or force (linear machine).\xa0As one side of the coil moves up through the magnetic field, a potential difference is induced (created) in one\xa0direction. As the rotation continues and that side of the coil moves down, the induced potential difference reverses\xa0direction. This means that the alternator produces a\xa0current\xa0that is constantly changing. | |
