Q.	without starter?
A.	heavy sparking at brushes
B.	it’ll start smoothly
C.	will not start at all
D.	depends on load
Answer» A. heavy sparking at brushes
Explanation: 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.
