Because a negative feedback system "closes the loop" based on a temperature sensor in the tip of the iron. This makes the temperature of the iron nearly constant whether sitting idle on the stand or being used to solder a massive joint. Without this negative feedback the temperature of the open loop iron would rise significantly when sitting idle on the stand and fall significantly when being used to solder a massive joint.

Electric rice cooker operation in open-loop or close-loop circuits?
if we set timimg for cooking rice then it is open loopbut thermostat in electric cooker can not give more temmp, than 100deg. so some microprocessor is controlling here .thus in this case it will act as closed loop system.
Is washing machine is open loop or closed control system and why?
closed loop system
What about sensitivity of a closed loop system?
Sensitivity of a closed loop system for a change in the system gain is 1/(1+GH)
Closed loop control?
The closed loop control refers to a system whereby an input forcing function is usually determined in part by the system response.
Why closed loop control system is much stable than open loop control system?
A Closed loop system basically will have a feedback which enables the rectification of the error in the main process,whereas it is not possible in an open loop system
Electric guitar control system is a closed-loop control system or not?
Yes it is
Why is the frog's circulatory system called a closed system?
It is called closed because all the plasma and its contents are contained within the vessels.
What us the earthworms transport system called?
closed circulatory system
What system in which both energy and matter are exchanged with the surroundings is called a?
Closed system
What has the author A Marcus written?
A. Marcus has written: 'Automatic industrial controls' 'Characterization study of an electric motor-transmission system for electric vehicles' -- subject(s): Automobiles, Electric, Electric Automobiles, Transmission devices
How do you add transmission fluid to a 2003 Saturn Ion?
if it is an automatic you cant yourself it is a closed system. if it is a manual i dont know.
Type of circulatory system in which blood is pumped through a network of vessels that form a closed loop?
Closed circulatory system or sometimes called cardiovascular system
What did Granville T Woods create?
Granville Woods received over 60 patents. His major inventions included an improved telephone transmitter, an electrical apparatus for transmitting messages, an induction telegraph system, a galvanic battery, an automatic What_did_granville_woods_inventcut-out for electric currents, an electric railway supply system, a regulator for electric motors, an egg incubator, and an automatic air brake.
How do you check automatic transmission fluid Mercedes Benz slk 230?
Unfortunately, Mercedes designed their SLK automatic transmissions as closed systems, without means of adding or draining fluid. Ostensibly, as a closed system, there is no need. How do you add fluid if you've had to replace a rear axle?
Where and how can you check the transmission fluid on my 1999 vw beetle with 2.0 gas engine and automatic?
You can't it is a closed system and it needs to be done by a professional.
What is the difference between a closed hydraulic system and an open hydraulic system?
A system which can exchange mass as well as matter with the surroundings is called anopen system.Example:- Heating of CaCo3 in an open bulb.A system which can exchange energy but not matter is called a closed system.Example:- Calcination of CaCo3 in a sealed bulb.
Open loop and closed loop systems?
Very generally, a closed-loop system will have some form of feedback that regulates the system behavior, whereas an open-loop system does not have this feedback. As a simple example, imagine you driving a car on a freeway: your car enters at 50 MPH and you want to be driving at 65 MPH. You know that if you depress the pedal at a certain degree for a certain amount of time, you will eventually accelerate the car to 65 MPH. In an open-loop system, you would have to make the best guess for the angle and amount of time you need to depress the pedal. In a closed-loop system, you are watching your odometer in order to see that you've actually increased your speed to 67 MPH and need to lay off the gas a bit. More importantly, if your car encounters a hill your closed-loop system will be able to recognize the fact that you require more acceleration to maintain your speed, whereas your open-loop system might slow down a lot. It should be clear from this example that closed-loop systems are in general more robust to changes in the system state that aren't considered in your model.
