By series parallel method of armature control how many different speed

1.	By series parallel method of armature control how many different speeds are possible?(a) 4(b) 8(c) 2(d) InfiniteI got this question by my college professor while I was bunking the class.I'm obligated to ask this question of Speed Control Using Armature Control in DC Motor in division DC Motors of DC Machines
Answer» The correct choice is (C) 2 Easiest explanation: Here two identical motors are coupled TOGETHER mechanically to a COMMON LOAD. Two speeds at constant torque are possible in this method—one by connecting the motors ARMATURES in series and the other by connecting them in parallel.
