hello people...
i learnt that the dc motor has a loop that rotates around two fixed magnets creating an emf. this emf is an alternating one.. so if i place a load across the loop, then AC current flows thru it...
the commuttator converts this ac voltage to dc voltage and this dc voltage appears across the brushes...
is there any way by which i can record this alternating voltage directly??? i am not interested in the dc output of the motor and want to see the ac voltage produced in the coil... can u please help out???
thank u....
