Why does a heating element get hot when current flows?
The current is doing work against the resistance of the material which makes up the heating element.Because it has resistance.-- Whenever electric current flows through a resistance, it loses energyequal to (current-squared) x (resistance).-- When we connect components in an electrical circuit, we use wire withthe least possible resistance, so as not to lose energy in the wiring.-- When we want to warm up the lab, we use wire with significant resistance,in order to have it dissipate significant energy and radiate heat.
Does a high temperature wire have more resistance?
Ideally, an electrical fuse should not have a high resistance. It will generally have some, because the way most cartridge fuses work is by heating a thin filament to the melting point when a certain current flows through it. The heating is resistive heating, which is given by the equation P = I2R, or power = the square of the current times resistance. <> The above is 100% correct, I just want to add: A fuse does not reduce the power in any way, It simply does not allow too much power to be taken. Example: You can use A 100amp fuse on A 10amp motor, The power supply will be 10amps because that's all the motor requires, but if there is a short or the motor is over worked the fuse will allow more chance of damage because its way too big for the job. Another: If A 10amp fuse is used to protect A 100amp motor the motor will blow the fuse everytime its terned on, because the fuse will not allow the motor the necessary power to opperate.
What bad things are there about friction?
It basically depends. Everything or nothing can be good about friction. It creates heat, and you might not want it to, but you might want it too (for instance creating a fire). It also slows things down, and you might or might not want it to slow down. You might want neither. It all depends.
Is effort diastance is equal to the resistance distance?
You can make any relationship you want between the effort distance and the load (resistance) distance. If you make them equal, then your lever has no mechanical advantage.
What is a material that conducts thermal energy?
If you want an example: Any metalIf you want an explanation:It is a material that allows heat to pass through it. If you heat up the end of metal rod the other end will become hot shortly afterwards because the metal conducts heat down it.
Why might you want to use a material with high resistance?
High Resistance Opposes the flow of Electricity that results into production of Heat and Light.
Why resistance of alloys decreases with temperature?
I thought the resistance of a material, with few exceptions, increased with temperature. Anyone else want to chime in???
What is the best shovel handle grip material?
You might want to go with this type of solid polyethylene D-grip handle to prevent calluses, but this material might wear out over time.
Why some materials offer different resistance?
SOunds like a homework question. But ok I'll answer. Ceramics is one major material used for resistance. BUT if you want to impress your teacher, you can say that ALL materials (even gold) offers some level or resistance, just very little)
Should dogs get high?
Well its not a great idea, as they might be allergic to the product to use them get high, but I'm not a dog so they might want to get high. it very unlikely though.
What can projector screen material be fixed with?
Projector screen material can usually be fixed with white seamless paper. One might want to look at the material used in the original screen to preserve quality.
Can you recycle fake plants?
It depends, what material the object is made of, if plastic and paper you might be able to, but anything eles you might want to throw it away.

Why did the resistance want Daniel to photograph the concentration camp?
which resistance? who is Daniel?
What is the use of universal high resistance voltmeter?
A voltmeter must have a very high resistance to measure voltage. A voltmeter is placed in parallel with the element that you are measuring. If the voltmeter has a low internal resistance, then all of the current will flow through the voltmeter instead of the element. You want all of the current to flow through the element, to get an accurate reading of the voltage. Conversely, an ampmeter must have zero resistance, because it is placed in series with the element.
