Answer 1

The setting of speed- load characteristic  parallel to itself is known as primary speed control and it is adapted as  on- line control.

Option A is correct.

Explanation:

• Primary speed control is a system applied in constant speed processes.
• It is used in single machine systems and is not suitable for multiple machines due to differences in speed setting.
• Primary speed control is governed by a speed droop.
• In primary speed controls, the speed load characteristic is adjusted by making suitable changes in the governor settings.
• This is achieved by using a speed motor.
