Which among the following controls the speed of D.C. motor?(a) Galvano

1.	Which among the following controls the speed of D.C. motor?(a) Galvanometer(b) Gauss meter(c) Potentiometer(d) TachometerI had been asked this question in an international level competition.I'd like to ask this question from The Design Problem topic in division Design of Control Systems
Answer» The correct choice is (d) TACHOMETER To explain: D.C. MOTOR is the motor which operates with the DIRECT current as in the CONSTRUCTION of DC motors slip RINGS not commutators and tachometer control the speed of DC motor.
