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.

How much heat is generated in a nuclear fusion?

Heat generated in a nuclear fusion depends on the resistance of the plasma and the current.


Why do materials with high heat capacities heat slowly?

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.


How much efficiency do you lose when using a home resistance heater?

You lose a lot of efficiency, since resistance heaters make heat off being inefficient.


Does heat depend on path?

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.

Does the amount of heat produced depend on the material of the conductor?

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.


What doesnt conduct heat well?

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.


How is heat made by electricity?

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.


How much heat is generated by 1 amp?

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.

Why does tungsten heat and light up but copper wire does not?

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.
