Which of the following is a characteristic of an open-loop system?

• Uses feedback

• Self-correcting

• Operates without feedback

• Requires sensors to adjust

A washing machine that stops at a preset time regardless of load weight is an example of:

• Open-loop system

• Closed-loop system

• Feedback-controlled system

• Sensor-driven system

A thermostat that adjusts room temperature by turning the heater on or off based on the current temperature is an example of:

• Open-loop system

• Closed-loop system

• Manual control system

• Relay control system

In a closed-loop system, feedback is used to:

• Ignore external disturbances

• Improve system accuracy

• Remove the need for actuator

• Eliminate the need for input

A factory conveyor belt automatically stops when a sensor detects that an item is at the correct position for packaging. This system is an example of:

• Open-loop control

• Manual control

• Closed-loop control

• Manual control
