In the above figure, suppose the physical load driven by the motor is reduced. As the motor speeds up, the CEMF ____________________ (increases, decreases), the net voltage across the armature ____________________ (increases, decreases), and the voltage at the junction between R8 and R9 ____________________ (increases, decreases). It is amplified by op amp 1, causing the summing amp to produce a voltage that is ____________________ (less, greater) negative turns Q1 on ____________________ (less, harder), and causes the SCR to fire ____________________ (sooner, later), which ____________________ (increases, decreases) the motor speed back to its desired

Question
