Answers
Explanation:
principal :an electric generator is the machine that generate electricity by rotating its rotor in a magnetic field .
construction :
generator consists of a rectangle coil (m n s t ) of insulated copper while place between two strong magnetic poles . two ends of the coil( M nst) are connected with brushes a and b of rings c and d respectively . the inner sides of the Rings are insulated . they are attached with an axle x , which can be rotated mechanically . brushes A and B are connected with a galvanometer that can measure the flow of current in coil MN ST
.working :
when the axle is rotated , lengths m n and ST move up and down respectively . since length m n and ST are moving in a magnetic field a current gets induced in this length caused by an Electromagnetic Induction .the direction of induced current in both the lens is given by Fleming's right hand rule
