Can anyone pls explain the working of electric generator?
Answers
Explanation:
Electric generators work on the principle of electromagnetic induction. A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet. ... The magnetic field will interfere with the electrons in the conductor to induce a flow of electric current inside it.
Answer:
as the armature is rotated about an axis , the magnet flux linked with the armature changes. therefore an infused current is produced in the armature..
Explanation:
a) let us suppose that the armature ABCD is rotating anticlockwise so that the arm AD moves inward and BC moves outward. applying Fleming's right hand rule , we find that the induced current in the armature and in the circuit. due to which G shows deflection towards the right.
b) after the armature has turned through 180° , it occupied the position . with the armature rotating in the same direction ( anticlockwise ) , BC moves inward and AD moves outward . this , again applying Fleming's right hand rule , we find the induced current in the external circuit flows in the opposite direction due to which the direction of deflection in the G ( galvanometre ) is towards the left.
thus we see that the direction of induced current changes in external circuit after every half revolution of the armature , i.e. after the armature has turned through an angle of 180 ° from it's initial position. hence, the induced current is alternating in nature......
hope it will help you.
