Bimetallic strips are typically found in the turn indicator circuit on vehicles. The opening and closing of the contacts makes the familiar clicking noise that we associate with turning on the blinker. This component is being replaced in the auto industry as more car models are being equipped with LEDs (Light Emitting Diodes). LEDs consume only a fraction of the current that their incandescent counterparts do and as such the current drawn is not sufficient to heat a strip. Both the LEDs and the solid state driver modules that are replacing the bimetallic strips are more durable, more reliable and usually have a life expectancy longer than the car they were installed in.

Does a barometer use a bimetallic strip?
yes
What is used to test the concentration of chlorine sanitizer?
Test strips is used to test concentration of chlorine sanitize. The test is dipped into the sanitize.
When was ethanol first used to fuel cars?
We hope that it will be used more in the future, because earth's store of patroleum will end someday. it was first used in ford cars, in 1908.
How might alternative logging practices such as cutting trees in strips of land and leaving strips next to then uncut or the replanting of slopes help reduce erosion?
If alternative logging methods are used, rainwater cannot flow as freely down the slope and carry away the soil.
Do cars and houses produce the same amount of pollution?
No, I think cars produce more pollution because of the gas being used.
How bimetallic strips are useful?
Bimetallic strips are useful in science experiments. They show you how one type of metal has a different thermal expansion rate than the other.
Why are bimetallic strips useful in thermostas?

Why are bimetallic strips used in thermostats?
The two metals chosen for the bimetallic strip have different modulii of thermal expansion, The bimetallic strip bends as the temperature changes and so the strip can be used to activate relays or other electronic switches and so work as a thermostat.
What are the 2 metal strips in a battery called?
a bimetallic strip
Bimetallic strips composed of two different metals each having a different rate of thermal expansion are used in?
Thermostats,.
What is a bimetallic strip and What is it used for?
it consists of strips madeof two different metals with different coefficient of expansion.use as fire alarm etc...
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.

Appliances bimetallic strips are used in?
Bimetallic strips are used in switches which are triggered by changes in temperature. Examples of appliances that use bimetallic strips include heaters, ovens, irons, coffee makers, and toasters. Various applications using bimetallic strips include: 1. Clocks - where temperature changes could cause errors in timekeeping. 2. Thermostats to regulate temperature in household heating systems and car cooling systems. 3. Some thermometers are based on bimetallic strips wound into a coil. 4. Circuit breakers in electrical devices are used to protect circuits from excess current by responding to any increase in temperature by cutting of the electricity supply. 5, Some photocell devices use a thermal relay consisting of a resistor and a bimetallic strip. The light causes the photocell to conduct electricity, causing the resistor to heat, thus causing the bimetallic strip to bend away from the electrical contact, keeping the lights or other load turned off. When it gets dark, the photocell no longer conducts, thus allowing the strip to cool and make contact. This design has advantages over using a magnetic coil relay in that there is some built-in delay and that there may be some inherent overload protection.
What is bimetallic strips used for?
Bimetallic strips were commonly used in thermostats. The two metals would expand at different rates and therefore bend. When a bimetallic strip, made of iron and brass [or any other metals] is heated, both metals expand differently, causing the bimetallic strip to bend. These bimetallic strips are used in fire alarms. The heat of the fire, causes the brass and iron strips to expand, ultimately resulting in the bending of the bimetallic strip, which on bending touches the screw adjacent to it, thus completing the circuit. Once the circuit is complete, the bell begins to ring. Thus the brass bends more than the steel, but on cooling, contracts more than the steel, thus causing the bimetallic strip to bend in the opposite direction.
What are the function of Bimetallic thermometer?
A bimetallic thermometer has a coil of metal strips in it. The metal strips are made of two different materials that expand/contract at different rates. Because they're connected together at one end, when the metals warm up or cool down, the coil changes shape. You use a bimetallic thermometer when you want an electrical circuit to close due to a change of temperature.
Where would you use what is a bimetallic strip?
A bi metallic strip is simply two different metal strips sandwitched together. When the bimetallic strip heats up it bends because one of the metals expands more than the other one when it gets hot. Bi metallic strips are used in cars. When the engine heats up too much the bi metallic strip bends to open the cooling valve (thermostat) to let coolant circulate around the engine body to cool it down. Then the strip bends back once it gets cool again. So its like a heat switch. Bi metallic strips are used for anything that needs a heat switch.
