When talking of heating elements in the electrical trade the unit of watts is used. The higher the wattage value of the device the higher its temperature output. Heating cables are measured in watts per foot as a way of measuring their heat output. The equation to find wattage of a device is to multiply the voltage of the device times the amperage of the device as stated on the device's nameplate or tag.
In most cases the temperature is linear throughout the length of the heating element. The actual temperature can be tested by using a laser spot temperature test instrument.

Is the heating element on a stove a chemical reaction?
No. It is a physical process cause be passing an electric current through a wire.
When checking an electric heating element you read voltage but no amperage What can you determine about the heating element?
the element has a open in it !
Why are heating elements of toasters made of alloy instead of iron?
1). You want the resistance of the heating element to be somewhat more than the resistance of a pure iron one. 2). When the heating element heats up to glowing, you don't want it to melt and fall to the bottom of the toaster in a blob. So you need a substance with a melting temperature higher than that of pure iron.
What if the input power is 208 volts line to line two phase 8 amps to a heating element vs 110 volts 8 amps to a heating element How is watts calculated?
To calculate watts, you need to multiply the voltage (in volts) by the current (in amps). For the 208 volts, 8 amps heating element: Watts = 208 volts * 8 amps = 1664 watts For the 110 volts, 8 amps heating element: Watts = 110 volts * 8 amps = 880 watts
How do you treat hardness in groundwater?
Hardness in groundwater could simply be treated by Heating the water to a considerable temperature. Chlorination and Distillation could also be applied to groundwater hardness treatment.
What is a ptc heating element?
Positive temperature coefficient heating element. Resistivity grow larger with higher temperatures so the heating element should be self regulating.
Why does the cord of an electric heater not glow while the heating element does?
The heating element of an electric heater is a "resistor", the cord which conducts the electricity is not. The resistance of the element of an electric heater is very high. As current flows through the heating element, it becomes red hot and glows. On the other hand, the resistance of the cord is low. It does not become red hot when current flows through it.
Does the wire in the electrical cord of an electric have a higher or lower resistance than the Heating element inside the kettle?
The wire in the cord has much lower resistance than the heating element. The heating element is a resistive or resistance heating element. Resistance in the quality of a substance or material that causes it to limit current flow, and it get heated up in the process. The heating element has all but the smallest fraction of the resistance in the circuit, so the heat, that thermal energy that get the water hot, is generated by the resistance of the heating element.

What is the resistance of a heating element pulling 17.8 amps and has 246 volts applied to it?
The formula you are looking for is R = E/I.
What element is used to heat toasters?
Element, meaning a heating element and not a natural element. The heating element is made by wrapping 'nichrome' wire around a flat sheet of Mica composite board. This then glows red hot, when mains electricity is applied to it. Nichrome is an alloy of Nickel and chromium. Chosen because it has electrical resistance and can stand repeated heating and cooling without melting.
What temperature setting is safe for a heated bird bath?
The size of the heating element in the bird bath will determine the temperature. This in a colder climate will want to use a larger heating element. Most areas should keep the water between 40 and 50 degrees.
Which heating element is used in a heater?
Heating element is the main part of the ironbox which gets heated as current passes through it. We have to use the material for heating element with features such as: 1) high melting point 2) high specific resistance 3) not easily oxidised. (most important point) Hence the alloy NICHROME ( nickel and chromium) is used for heating element because it is not oxidised even at high temperatures.
How does a heating pad work?
Heating pads contain heating elements that convert electricity to heat by passing current through a conductor (usually a wire). This process is variously referred to as resistive heating, ohmic heating, or Joule heating. The amount of heat generated is proportional to the square of the applied current multiplied by the resistance of the conductor. If SI units are employed (amperes for current and ohms for resistance) the unit of heat energyis called a joule.
What metal is the heating element in a kettle?
It's basically the same as the glow wires in a toaster, or the filament in an incandescent light bulb. When a current is passed through the element, the resistance makes the element heat up.Another AnswerWhen an electric current passes through the heating element, it does work on the heating element, water, and the kettle itself. This causes the internal energy of the element, water, and kettle to rise, and this is accompanied by an increase in temperature. When the temperature exceeds that of the surroundings, some energy is lost to the surroundings through heat transfer. The equation that describes this is:W - Q = [m c (T2 - T1)]water +[m c (T2 - T1)]kettleWhere:W = work done (joules)Q = heat transfer (joules)m = mass (kilograms)c = specific heat capacity (joules per kilogram kelvin)T2 = final temperature (kelvin)T1 = initial temperature (kelvin)

How glue gun heating element works?
An electric current heats a metal tube that the glue is forced through.
