Depends on the voltage. Wattage is Volts x Amps. Resistance (ohms) is Volts divided by Amps.
So on a 120V circuit, it would draw 41.66 amps. To do that, it would need a resistance of 2.88 ohms. But on a 240V circuit, it would draw 20.83 amps. That would require a resistance of 11.52 ohms.
Determine the circuit voltage, then use that to figure the amps, then use that result to calculate the resistance necessary.
Heat generated in a nuclear fusion depends on the resistance of the plasma and the current.
if you are talking about the strips that you put on your forehead it isn't an LCD strip instead there are different thermochromic inks applied to different parts of the strip. when heat is applied to the inks they change colour and with the use of different inks, they change colour at different temperatures because of this, you can see your temperature (: help much?
It doesn't have that much metal.
No. Resistance and density are unrelated properties; for example, salt water is denser than oil, but has a much lower resistance.
I read this once-silver is the best,I think. Copper may be second. Aluminum is not bad and may be third. With more thought, I do not think speed is an issue- what matters is resistance- how much energy is lost to heat- I am guessing speed and resistance are related. but I am not cetain. Hopefully some EE will jump in here.
Power consumed by a resistance is I2R
Heat generated in a nuclear fusion depends on the resistance of the plasma and the current.
because by definition heat capacity is how much heat the substance needs to change its temperature by 1 degree. It "stores" heat and delivers it back slowly. It has nothing to do with heat resistance which is how much heat it allows through it.
You lose a lot of efficiency, since resistance heaters make heat off being inefficient.
Not really, if you're referring to heat transfer, then the heat will use the path of least resistance. So the heat doesn't rely on the path as much as it does on the material that the heat must travel through.
a short or too much resistance thus heat
Yes, resistance in a conductor causes energy losses due to heat. Metals such as Gold and Platinum have very low resistance but they are very expensive so Copper and Aluminium are used instead which are much more affordable but have higher resistance.
Heat insulation is defined as the resistance to the flow of heat offered by a material when it is subject to a change in temperature. Objects that put up a lot of resistance to heat flow don't conduct heat well, and are called insulators. Some examples of insulators are wood, rubber and glass. Things that do conduct heat well don't offer much resistance to heat flow. Many metals fall into this category, such as aluminum, copper, and gold. See the link below for more information on heat conduction.
There are many ways how electricity can create heat. For example, passing a current through a wire of high resistance (i.e. a resistor) will generate heat, though not much.
The heat generated by an electric current is in watts, Current x volts. So current alone is not enough to define it. By Ohms Law, Volts = Current x Resistance, so another way of expressing watts is (Current squared) x Resistance. If you know the current andthe resistance you can get the wattage, which will give you the heat generated.
the right amount is £70.90
Copper has much less resistance, so the electricity flows thru it with little heat, where as the tungsten resists the flow and generates heat, that you see as light.
