In the figure given below, a coil is placed between two permanent magnets and it is rotated with the help of an axle, on which two rings R1 and R2 are internally attached. B1 and B2 represents metallic brushes. G represents galvanometer.
The current flowing through the circuit reverses direction periodically, such a current is called alternating current. The current can be made direct by ___.
What is the function of the split rings of an electric generators and also discuss the function of the brushes?
