We have seen that the electric iron, geyser and air conditioner get switched off automatically
after sometime. How does this happen?
Answers
The working of an electric iron is very simple – it takes current from the mains and heats up a coil inside it. This heat is then transferred to the base plate which is pressed against clothes to remove creases.
Back when I was learning how to iron my clothes, I was rather annoyed by the whole process. For no reason whatsoever, it kept switching on and off of its own accord. As much as I was irritated by this, I was also intrigued by the strange phenomenon. Thankfully, I soon came to know that it was the ‘automatic power cut’ feature that prompted this action in the iron.
The electric iron that we use to press the creases out of our garments also contains a thermostat, which makes sure that the iron doesn’t get too hot if it’s kept switched on or left unattended for an extended period of time. Let’s take a look at exactly how the mechanism works.
An electric iron relies on a basic combination of heat and pressure to remove creases from clothes. When an electric current is passed through a coil (or any other heating element present in the iron), it gets very hot. This heat is then transferred to the base plate (the smooth, flat surface that you place against clothes while ironing) through conduction, which elegantly and precisely irons your clothes.
Answer:
Due to the thermostat.
A thermostat is a device that automatically regulates temperature, or that activates a device when the temperature reaches a certain point.
A thermostat is essentially a heat-activated switch, a thermostat has a temperature sensor that causes the switch to open or close, completing or interrupting an electrical circuit that runs the house's heating or cooling system. It can do this job either mechanically or via electronic circuitry.
