If a DC Generator is rotating and genertating electricity, for a DC motor.these energies are going to motor by two wires (possitive and negative).Now consider if we cut one of the wires of DC generator for example thepossitive one, the Motor will be stoped of rotating but the Generator is still runing, Now I want to know where all those currents and energies generated by the DC generator are going?
