How does a conductor absorb heat?
A conductor does not absorb heat, it conducts heat so that the heat is evenly dispersed. It seems like it absorbs heat but it transfers heat to somewhere else.
Why does electrical resistance cause heat to be produced?
Energy is given off in the form of heat because energy cannot be created or destroyed so it has to go somewhere in the form of light or heat.
Would feather and a nail reach the ground at the same time?
On Earth, no. Air resistance would slow the feather way down. However, dropped on somewhere without an atmosphere (like the moon), they would reach the ground at the same time.
If you drop a bullet and fire a rifle at the same time will the bullets hit the ground at the same time?
Technically, yes. There are many variables to consider though like recoil, wind resistance, the barrel of the weapon, etc. The Mythbusters actually did that test. You could probably find that video somewhere.
What is the explanation for the mechanism of electric heat?
Electric heat is sometimes looked at under the heading of resistance heating. Somewhere in the heater is a resistive material through which the electric current is passed. Recall that there is always a bit of resistance in wires and such, but not much. This resistive element is selected because it resists current flow. It's a conductor, but not a very good one. When current is forced through this resistive material, it gets hot. Making current flow through a material is easy or hard. There's a fair amount of variation across materials. The specific material and its atomic or molecular structure will determine what Fermi energy levels the valence electrons are hanging out in. If these electrons can be easily accelerated by applying a voltage, the material is a conductor. The so-called conduction band is low enough that it overlaps the energy bands of the valence electrons. If the conduction band is very high above the energy of the valence bands, the material is an insulator. And there are materials that exhibit properties across an array between these extremes. It's a matter of selecting something that conducts, but well. By picking something like nichrome wire and incorporating it in an electric heater as the resistance medium, we can get that wire to generate heat by forcing electric current through it. A kitchen toaster has nichrome wire strung inside it. That's what's glowing and toasting the slice of bread. Got a hair drayer in the house? Yup, there's a nichrome wire heater inside.
What elements are good at conducting heat and electricity?
super conductive elements, beena while since i looked at a periodic table but i believe it is broken into parts. being non conductive, partial conductive, conductive, and super conductive. i thinkt here may even be a 5th section somewhere. if memory serves the further right you go the more conductive it becomes.
How do you check the headlamp resistance in th earth connection?
The resistance (ohms) between the headlamp "earth" connection and the vehicle battery NEGATIVE connection should be near zero. Although zero ohms is technically not possible in anything short of a superconductor, the resistance should not be much more than 1. If the resistance is much more than that, you should clean rust/corrosion from connectors and use some kind of rust inhibiting/conductive material to improve the conductive properties of the circuit. The above is true, but not easy. If in doubt of any ground connection in a car, just run another ground wire from the item to somewhere you know is a good ground (car frame, ground buss, negative battery cable, etc)
Were will resistance 3 be set?
Resistance 3 will be set somewhere within the United States of America during the 1950s.
Why the current is reduced as electrons move through a conductor?
I assume you are referring to electrical resistance. Basically, some electrons in a current will collide with atoms or other electrons, and lose energy in the process. This energy, of course, has to come from somewhere - so the current loses energy.
Why might there be a charge in temperature when electrical current is passed through a conductor?
If the conductor has any resistance at all, then some energy is lost from a current flowing through it. Since energy is never destroyed or caused to disappear, the energy lost from the current must go somewhere. Almost always, it leaves the conductor in the form of heat. We encourage this process, bend it to our will, and use it to our advantage, in the design of toasters, hair dryers, space heaters, and incandescent light bulbs.

What are the difference between semiconductors and semimetals?
A conductor is just that - something that conducts electric current. A semiconductor, however, is a material that can be and is used because by doing some things to it, we can cause its resistance to vary dramatically over a fairly wide range of values. We can cause it to conduct with little resistance, and we can cause it to resist current flow completely and prevent current from flowing. The material is a semiconductor, and it "sort of" conducts - either well or poorly or something in between, depending on how the device is made and on what we tell it to do. Conductor will pass electrons by the laws of electrical conductivity. Semiconductor will pass electrons basically only one way.Conductors, like copper, are materials that simply conduct electricity from point A, such as the negative terminal of a battery, to point B.Semiconductors are materials that conduct electricity from point A to point B, but have high high resistance. Many conductors can be modified to have unique properties when electricity is applied, such as in transistors. Put simply, semiconductors have an electrical conductivity somewhere between that of conductors (gold, copper) and insulators (wood, rubber).A conductor allows an electric current to flow through it equally well in either direction. The amount of current which flows depends only on the amount of resistance of the conductor and on the amount of voltage applied across it. The direction of flow can always be considered as being from the positive to the negative pole of the source of the voltage applied, so the direction of flow through a conductor is always determined by which end of the conductor is connected to the positive pole of the source. A semiconductor allows an electric current to flow very strongly in one direction (this is known as the forward current) and very weakly in the opposite direction (which is known as the reverse current). The amounts of current which flow in each direction depend partly on the amount of the voltage applied but mainly on the forward resistance (which is relatively low) and the reverse resistance (which is always very high). So, unlike a conductor, the flow of current through a semiconductor is not the same amount of current whichever way the voltage is applied. The direction in which a semiconductor allows the forward current to flow depends on whether it is a p-type semiconductor or an n-type semiconductor. How are semiconductors made? Certain elements, such as Germanium or Silicon, are not naturally semiconductors but can be made into semiconductors by melting them and adding very small amounts of other chemicals. This process is called doping. Whether a p-type semiconductor or an n-type semiconductor is produced depends on the type of doping chemical used.
What means the resistance of a liquid to flowing?
There is either a restriction somewhere or the fluid viscosity is too high.

What is A Resistor In A conductor?
Resistors and conductors are actually two sides of the same story. They both conduct electricity and they both resist conducting electricity. The difference is how well they conduct electricity. Copper, Silver and Aluminum are examples of brilliant conductors. They resist very little. Coal-fibers and various metal oxides are examples of poor conductors. They resist much more and falls into the category of being a resistor. The comparison can easily be made with a water pipe-line. A huge dimension can carry a lot of water (This is electrical current). It can also contain high pressure (In this analogy, that would be Voltage) A very small dimension can not carry much water at all (The current is limited. This is what physically happens in a resistor.) The water pressure is the same, then the big pipe might fill a bathtub in 30 seconds where as the small pipe would maybe need 10 minutes or more. It works "exactly" the same way with electric components as conductors and resistors. Some people claim that a conductor is the opposite of a resistor. This is a wrongful interpretation although it seems to make sense... They are both conductors of voltage (water pressure as an analogy). A resistor only limits the current, Amount of water in previous analogy, somewhat, this depending on the specifications of the resistor. A conductor is a good leader of the electricity and a resistor is damping the electricity.
What are track lighting fixtures?
Track lighting is a method of lighting where light fixtures are attached somewhere on a continuous track device, which contains electrical conductors.
Why geranium is known semi conductors?
A geranium is a flower, and not a semiconductor. The element Germanium, however, is a semiconductor, which means it has an electrical conductivity somewhere between that of a metal and an insulator.
