Question

Need help with 9,10,11

9. In the illustration at right, notice the position of the wire loop relative to the permanent magnets, and notice the position of the brushes-touching both segments of the commutator. What can you say about this arrangement? Why is it 'special. 2 marks 10.An output waveform like the one shown at right, is accomplished by: (choose one) a. Increasing the number of turns of wire for one loop. b. Using more than one loop of wire. 11.A DC generator's armature (ignore the shaft) can be said to be made up of what three parts?

Answer 1

O The arrangement is simple view it an dynamo or generator. The permanent magnet produces flux. an ever an conductores are soleled in that steady flas Halhen emf will be induced in it. The emf is collected from the commentator and is supplied to - the load from (+ -) ferminale - as Increasing number of turno increases emf magnitude but not Cyclco. b) cycles of enf Increasing number of loope increases no. of : ophon (6) is correct ☺ Dc generator Anmatur: 11 Armature core 2) conductore placed in slote 3) Brushes and commutator to collect current from conductors.
