AC Generator 10th class physics chapter 15 | ac generator physics wallah sabaq in urdu hindi 15.7 AC Generator number of magnetic lines of force passing through the coil. The number of lines of magnetic force passing through the coil will be maximum when the plane of the coil is perpendicular to the lines of magnetic force. The number of lines of magnetic force will be zero when plane of the coil is parallel to the lines of force. Thus, when a coil rotates in a magnetic field, the induced current in it continuously changes from maximum to minimum value and from minimum to maximum value and so on. This is the basic principle on which an A.C generator works (Fig. 15.16). Fig. 15.16: A.C Generator The armature is arranged so that it can rotate freely in the magnetic field. As the armature turns, the wire loops cut through the magnetic field lines and induced e.m.f. will be produced. The e.m.f. developed by the generator depends on the length of the wire rotating in the field. Increasing the number of loops in the armature, increases the wire length, thereby increasing the induced e.m.f Current from a generator When a generator is connected in a closed circuit, the induced e.m.f. generates an electric current. As the loop rotates, the strength and the direction of the current changes as shown in Fig. 15.17. When the plane of will is perpendicular to field, the number of lines of magnetic force passing the trough it is maximum.
