Explain working of generator. |

Answer» Hey!Working of a generator :1.Let abcd be a rectangular coil between North and south poles of a bar magnet 2.Attach abcd to a battery with slip rings b1 and b2(Slip rings are used to rotate the rectangular coil)Now, working 1.When the two rings are rotated such that arm ab moves up and CD moves down, current is generated in the coil kept in magnetic field2.by applying Fleming\'s right hand rule, the induced current is set up along the direction ab and cd3. After half a rotation arms cd moves up and ab moves down. As a result the direction of induced current changes that is, current now flows in direction dcba (earlier current was flowing in abcd) 4.the current in the slip rings also reverses and flows from b2 to b1(earlier b1 to b2) 5.such a current changes direction after equal intervals of time and hence called an ac generator too Hope you understood ?? Generator is a machine that converts mechanical energy into electrical energy. It works based on principle of faraday law of electromagnetic induction.Generators are basically coils of electric conductors, normally copper wire, that are tightly wound onto a metal core and are mounted to turn around inside an exhibit of large magnets. An electric conductor moves through a magnetic field, the magnetism will interface with the electrons in the conductor to induce a flow of electrical current inside it. |
