can anyone solve this question
Answers
Answer:
construction: the main components of ac generator are rectangular coil , strong magnets , rings, brushes , axle
working : 1. when the axle is rotated with the help of a machine from outside, the coil ABCD starts rotating .
2. on rotating the axle , the branch AB move upwards and branch CD move downwards hence coil ABCD rotates clockwise.
3. according to Fleming's right hand rule , electric current flows in the direction A to B to C to D . therefore, current flows from B2 to B1 in the external circuit through galvanometer.
4. after half rotation , the branch AB and CD exchange their position and the induced flows as D to C to B to A.
5. since , branch BA is in contact with brush B1 and branch DC is in the contact with B2 , current flow from B1 to B2 in the external unit that is in the direction opposite to the previous half rotation.
6. this repeats after every half rotation and in this way , alternate current is produced using AC generator.
