PLEASE ILLUSTRATE AND MAKE SURE TO WRITE IT ON A PIECE OF PAPER THANK YOU SO MUCHThe field coils of a six-poles D. C. generator each having 600 turns, are connected in series. On the excitation of the field, there is a magnetic flux of 0.024 Wb/pole. If the field circuit is opened in 0.24 second and residual magnetism is 0.0024 Wb/pole, calculate the average voltage which is induced across field terminals.
