Closed Loop vs Open Loop Systems Quiz

What is the main characteristic that differentiates a closed loop system from an open loop system?

• It does not require input

• It does not require feedback

• It uses feedback to adjust the output

• It always runs on a set time

Which of the following is an example of an open loop system?

• Cruise control in a car

• Thermostat

• Simple toaster

• Robotic arm with sensor feedback

In a closed loop system, what is the role of feedback?

• To start the process

• To monitor and adjust the output

• To stop the system when needed

• To reset the system

Which of the following would best describe the function of a thermostat?

• It heats the room for a set amount of time

• It adjusts the room temperature based on the desired set point

• It cools the room when the weather gets hot

• It turns on the heater when it gets dark outside

Why might an open loop system, like a washing machine with a set cycle, be disadvantageous?

• It is more expensive than closed loop systems

• It requires constant monitoring by the user

• It cannot adjust based on how clean the clothes are

• It requires feedback to operate

Which of the following is a benefit of using an open loop system?

• It offers greater accuracy

• It is simpler and more cost-effective

• It adjusts automatically to external conditions

• It uses sensors to monitor the output

What type of system is a microwave with a pre-set time?

• Open loop system

• Closed loop system

• Hybrid system

• Manual system

In a closed loop system like cruise control, what does the system do when it detects a change in speed due to an uphill slope?

• It continues at the same power level

• It automatically increases the power to maintain the set speed

• It turns off the engine

• It alerts the driver to adjust the speed

Which of the following would be an appropriate situation for an open loop system?

• Controlling the temperature in a house

• Operating a robotic arm in a factory

• Timing a traffic light in a low-traffic area

• Controlling the speed of a car on a busy highway

What is a disadvantage of a closed loop system?

• It cannot adapt to changing conditions

• It is less accurate than an open loop system

• It is more complex and expensive

• It always operates at maximum power
