What is the function of the rods?
A lightning rod (US, AUS) or lightning conductor(UK) is a metal rod or metallic object mounted on top of a building, electrically bonded using a wire or electrical conductor to interface with ground or "earth" through an electrode, engineered to protect the building in the event oflightning strike. If lightning hits the building it will preferentially strike the rod and be conducted to ground through the wire, instead of passing through the building, where it could start a fire or cause electrocution.A lightning rod is a single component in a lightning protection system. Lightning rods are also called finials, air terminals or strike termination devices. The lighting rod requires a connection to earth to perform its protective function. Lightning rods come in many different forms, including hollow, solid, pointed, rounded, flat strips or even bristle brush-like. The main attribute of all lightning rods is they are conductive.
How do fire doors work?
Fire doors are used to stop fires or smoke from spreading into different areas of a building. Some fire doors have furry strips round the edges, these are called intumescent strips. The fibres in the strips swell when they get hot and stop smoke going round the edges of the door. The doors themselves are made up of layers of fireproof material which means that it takes longer to burn through the door. Most common fire doors protect the rest of the building for around half an hour only because of the intsumescent strips and the fireproof material actually on the doors.
What is a material made from the mixture of different metals?
Sometimes different metals are alloyed, and sometimes they are simply joined. Plated metals would be the most common - such as galvanized iron sheet. Thermocouple elements may be made from bi-metallic strips. Iron and brass are common metals thus amalgamated for this use. Alloys are in general of wide use - cupro-nickel is a very common heating element for electrical appliances. Magnesium is often alloyed with aluminum to improve its strength. For tool steels, vanadium, chrome, and nickel are common additives.
What element is used for the shiny trims on cars?
Chromium.The chemical element chromium is used for the chrome plating of metal strips for automobile trim.
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!
How do you separate copper strips from sulfur powder?
To separate copper strips from sulfur powder, you can use a process called filtration. Mix the copper strips and sulfur powder with water to form a mixture. Then, pass the mixture through a filter paper to separate the solid copper strips from the sulfur powder, which will remain in the filter paper.

Difference between bus bar and bus duct?
Bus bars are actually simple conductor strips of copper using for connection between one system to another.for example transformer to panel. bus ducts are enclouser of that bus bar
What will happen when the aluminum strips in an electroscope are replaced by plastic strips and a charged body is brought in contact with the metal clip?
The electroscope will not show any deflection as plastic is an insulator and does not allow the flow of charges. The charged body will not induce any charge separation in the plastic strips, so there will be no movement of charges to indicate the presence of a charge on the electroscope.
How will plastic strips help potatoes grow on farmers fields?

How fast does copper strips rust?
i don't care that's a stupid question dude
What kind of materials are used the in magnetic strips of ATM cards?
Iron compounds and plastic.
Why copper strips are used in meter bridge wire?
Copper strips are used in a meter bridge wire due to their excellent conductivity, which allows for accurate measurement of resistance in the wire. The low resistance of copper helps minimize any potential measurement errors caused by the resistance of the connecting wires.
Suggest why it is useful that the plastic strips break down naturally.?
So that the plants arnt disturbed
What is indicated when the paper bits move towards the rubbed plastic strip?
The movement of paper bits towards the rubbed plastic strip indicates the presence of static electricity. When the plastic is rubbed, electrons transfer from the plastic to the paper, causing the paper bits to be attracted to the strip due to opposite charges.
What exactly are diabetic strips?
Diabetic strips are thin plastic pieces that are inserted into a blood glucose monitor. This is how you can find out your glucose level in your blood. http://www.ehow.com/about_4602102_diabetic-test-strips.html#ixzz1PSr1cS1H
Can metal strips be welded or soldered?
Yes, metal strips can typically be welded or soldered depending on the material. For example, aluminum strips can be welded with specialized equipment, while some metals like copper can be soldered. The specific welding or soldering method will depend on the metal type and its application.
