A bimetallic strip is a strip made from 2 different metals. It is designed to bend one way if it is warm and the other way if it is cold. The hotter it gets, the more it bends. In any thermostat, the electrical contacts bend apart as the target temperature is reached. The only difference between a heating thermostat and a cooling thermostat is which side of the bimetallic strip faces the other contact. In a heating appliance, the thermostat knob turns a screw to add resistance to the motion of the contacts so they must get hotter to separate as the screw is tightened. So the tighter the screw is turned, the hotter the appliance is allowed to get before the contacts separate.

What is bimetallic strip made of?
A bimetallic strip is typically made of two different metals fused together, such as brass and steel or copper and iron. These metals have different coefficients of thermal expansion, causing the strip to bend when exposed to temperature changes.
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.
What happens to the bimetallic strip when the iron is hot?
When the iron is hot, the bimetallic strip will bend towards the iron due to differential expansion of the two metals in the strip. This bending occurs because the metal with higher thermal expansion coefficient will expand more, causing the strip to curve towards that side.
What way does a bimetallic strip bend with iron and brass?
When heated, a bimetallic strip made of iron and brass will bend towards the brass side due to the different coefficients of thermal expansion of the two metals. This is because brass expands more than iron when heated, causing the strip to curve towards the side with greater expansion.
Would brass or iron expand in a bimetallic strip?
Brass and iron have different coefficients of thermal expansion, so when exposed to a change in temperature, they would expand by different amounts. This difference in expansion causes the bimetallic strip to bend due to the unequal expansion of the two metals.
What uses bimetallic strip?
Appliances like electric iron, which need a cut off from the electric current from time to time as the appliance is heated adequately, use bimetallic strip for this.
Can anyone explain the use of a bimetallic strip in heat regulation in an electric iron?
When the temperature of the iron increases, the bimetallic strip bends upwards. This breaks the contact between the strip and the heating coil. When the temperature falls, the bimetallic strip bends down and the contact is restored.
How do you make a circuit using bimetallic strip?
The bimetallic strip is made of two different metals, bonded together. The two metals have different temperature expansion coefficients, so when the bonded assembly is heated or cooled, it curves one way or the other, allowing a switch to be opened or closed.
Can we use bimetallic strip in iron box?
yes, in automated iron boxes

What does the bimetallic strip in an electric iron do?
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 bimetallic strip. This little fixed plate will touch the free end 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 bimetallic 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.Thats the idea!
What would use more volts an electric razor and electric iron?
Electric Iron by far.
What is an electric flat iron?
An electric flat iron is a type of clothes iron that runs on electricity. The first electric flat iron was invented by Henry W. Seely.
