It is used as a thermostat.
A thermostat is a device used to control the temperature of any equipment, in this case an electric iron.
Two little strips of different types of metals are welded or brazed together. These little strips will be mounted inside the the iron near to the hot plate, held down just at one side.
An electrical contact will join the bimetallic strip into the electrical circuit of the iron. Another little flat metal plate will be mounted near the free end of the bimettalic strip. This little fixed plate will touch the free enf of the bimetallic strip.
So now you turn the iron on. The irons' hot plate heats up. The bimetallic plate heats up too as it is close to the hot plate.
Ok, now is the clever bit someone once thought out. The two strips of metal heat up and expand. As the properties of the metals are different they will expand at different amounts. As the two strips are stuck together the bimetallic strip will bend.
When it bends it will eventually bend away from the fixed plate. Assuming its been installed with the bimettaic strip the right way around! because the strip will bend to the side which has the metal that expands less. When it no longer touches the plate the circuit will turn off. And hence the power is turned off to the iron.
So how come that dial makes the iron hotter or less hot? When you are twisting the dial you are actually squeezing some tension into the bimetallic strip so that it will have to get hotter before it will bend away from the contact and hence break the circuit.

Appliances bimetallic strips are used in?
Bimetallic strips in appliances are commonly used in thermostats to regulate temperature. As the temperature changes, the bimetallic strip bends, causing it to open or close an electrical circuit to control the appliance's heating or cooling functions. This mechanism helps maintain a consistent temperature within the appliance.
Are bimetallic strips used for On Off control?
Bimetallic strips are commonly used as temperature-sensitive sensors in devices that require automatic temperature regulation, such as thermostats. The bimetallic strip bends in response to temperature changes, making it a useful component for on/off control systems where temperature is a key factor.
Is bimetallic strip is used in spoon?
A bimetallic strip is not typically used in spoons. However, bimetallic strips can be found in devices such as thermostats, thermometers, and switches due to their ability to bend when exposed to temperature changes, which can be used to control electrical circuits.
Which two metals are used in bimetallic strip in a tube light starter?
Bimetallic strips used in tube light starters typically consist of nickel and iron. These metals are chosen for their differing coefficients of thermal expansion, which allows the strip to bend when heated by the electric current passing through the starter.
How does the concept of linear expansion help the fabrication of bimetallic strips Explain the working g of bimetallic strips in a thermostats?
The concept of linear expansion is used in bimetallic strips to create a temperature-sensitive component. Bimetallic strips are made by bonding two different metals with different coefficients of thermal expansion. When exposed to temperature changes, the metals expand or contract at different rates, causing the strip to bend. In a thermostat, this bending action controls an electrical switch, regulating the temperature by turning a heating or cooling system on and off.
Bimetallic strips composed of two different metals each having a different rate of thermal expansion are used in?
Bimetallic strips composed of two different metals with different rates of thermal expansion are used in devices like thermostats and thermometers. When these strips are heated or cooled, they bend due to the different expansions of the metals, which can be used to control switches or indicate temperature changes.
WHAT IS a bimetallic thermometer used for?
A bimetallic thermometer is used to measure temperature by utilizing the different rates at which two metal strips expand with heat. When the temperature changes, the bimetallic strip bends, causing a needle or pointer to move on a scale to indicate the temperature. Bimetallic thermometers are commonly used in household appliances, industrial settings, and HVAC systems.
Why are bimetallic strips used in thermostats?
Bimetallic strips are used in thermostats because they have the property of bending or curving when heated or cooled. This bending action is utilized to open or close electrical contacts in the thermostat, triggering the heating or cooling system to turn on or off based on the temperature changes.

What is a bimetallic strip and where can it be used?
A bimetallic strip is made of two different metals bonded together, which have different coefficients of thermal expansion. This causes the strip to bend when heated or cooled. Bimetallic strips are often used in thermostats, temperature switches, and circuit breakers to control temperature-sensitive mechanisms.
How bimetallic strips are useful?
Bimetallic strips are useful because they are designed to bend or curl when exposed to temperature changes, due to the different thermal expansion coefficients of the two metals they are composed of. This bending action can be used in devices such as thermostats to control temperature, switches to break or complete an electrical circuit, or in mechanical gauges to indicate temperature changes.
What is a bimetallic?
A bimetallic thermometer uses a bimetallic strip wrapped into a coil. This strip usually consists of either steel and copper or steel and brass. A bimetallic thermometer is a type of thermometer made with a couple metal strips. They have differing thermal expansions that are brazen together. Any distortion in this apparatus caused by variations in the temperature is used to measure the temperature.
