Electrical Engineering XYZ MCQ
The output of the system has an effect because of the input quantity, then such a system is a:
- Closed loop control system
- Open loop control system
- Either of these
- None of these
Correct answer: 1. Closed loop control system
Explanation: A closed-loop control system is characterized by the output influencing the input quantity to uphold the desired output value. By incorporating feedback, an open-loop system can be transformed into a closed-loop system. The inclusion of feedback facilitates automatic correction of output changes caused by disturbances. Consequently, the closed-loop control system is commonly referred to as an automatic control system.
