A bimetallic strip is often used in thermostats because it is quite simple to make and responds predictably to changes in temperature. The bimetallic strip is pretty much what it sounds like - a strip made from two metals. Inthermostatsit is common to make one side out of steel and the other out of copper - then bond them together. they are formed into a curving spiral. Different metals have different coefficients of thermal expansion so as the temperature changes, the spiral strip either curls up or uncurls as one side expands or contracts more than the other. The control isattachedto one end of the strip so that as it curls or uncurls, it rotates the control.Sometimes the control is a simple Mercury switch that closes a contact whenrotatedone way and opens the contact when rotated the other. Sometimes one end is attached to a power source and the other end is connected to an electric contact, which moves as the strip curls and uncurls.
You can also attach it to a pointer and have it point to temperatures on a dial.

What is the advantage between a bimetallic thermometer and an ordinary thermometer?
If you mean by an "ordinary" thermometer, a mercury thermometer, the bimetallic type can measure a far greater range of temperature (mercury freezes at -38oC and boils at 356oC making it useless in the polar regions or for measuring high temperatures).Bimetallic thermometers are also more robust; mercury thermometers are usually made from glass and are fragile.
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.
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!
Any 5 gadgets in which bimetallic strip is used?
They're all thermostats of on kind or another: home, car, stove, hot-water heater,
How could a bimetallic strip perform a practical task in life?
bimetal stip is next to the contacts it make your oven,iron and air conditions unit work that is when ever the contacts touch from how high you put it and it heat up and the iron and brass bends
What is abimetallic coin?
A bimetallic coin has two metals, usually copper and nickel.
How much a 2 euro coin weighs?
A bimetallic 2 Euro coin (not to be confused with a copper 2 Euro Cent coin) weighs 8.50 grams.
How heavy is a 1 euro coin?
The British one pound coin weighs 9.5 grams.
What is my repvbblica italiana L.500 1960?
Repvbblica Italiana L500 is a lire bimetallic coin. It is valued at $2, uncirculated grade in the Standard Catalog of World Coins.
What happens when bimetallic strip is heated?
The bimetallic strip bends.
How much does a bimetallic strip cost?
The cost of a bimetallic strip can vary depending on the size, material, and manufacturer. On average, a bimetallic strip can range from a few dollars to tens of dollars.
Which European coins have a silver outside and a gold center?
None that I know of. The idea behind having a different metal in the core of any coin is to increase the coin's structural integrity. Gold is quite soft and though valuable, would make a poor choice for any coin. You may be thinking of a so-called bimetallic coin. Many countries issue these coins, but they're made of brass and copper-nickel, not gold and silver. Examples are the Canadian $2 coin, the European €1 and €2 coins, and the British £2 coin.
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.
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.
What is a 1 Euro coin made of?
€1 coins are bimetallic; that is, they're made in two parts, each with a different metal. The outer ring of the coin is made of nickel-brass, an alloy composed of 75% copper, 20% zinc and 5% nickel. This alloy has a gold colour. The inner core of the coin is made of an alloy consisting of 75% copper and 25% nickel.
What objects are bimetallic used in?
Circuit breakers.
Does the bimetallic strip bend when heated?
yes
