Answer» The correct answer is (a) Heavy sparking at BRUSHES For explanation I WOULD say: It would CAUSE intolerably heavy sparking at the brushes which may DESTROY the commutator and brush-gear. Sudden development of large torque will cause mechanical shock to the shaft, reducing its life. Such heavy CURRENT cannot be generally permitted to be drawn from the source of supply.
