What causes resistive heating and then a fire?
Resistive heating occurs when electrical current flows through a material with resistance, causing the material to heat up. If the heat generated is not properly dissipated, it can accumulate and lead to a fire if the material's ignition temperature is reached. Overloading electrical circuits, using damaged electrical cords, or faulty connections are common causes of resistive heating and potential fire hazards.
Examples of resistive heating?
In a toaster, the house current from the outlet passes through a wire with some resistance. Household electricity is supplied at a nominal 117 volts AC. If 'R' is the resistance of the wire in the toaster, then the power (heat) dissipated by the wire is E2/R = (117)2/R watts of heat. Notice that as long as the voltage remains constant, MORE resistive heat is dissipated from a SMALLER resistance.
Is a microwave a resistive load?
Yes, a microwave is a resistive load as it converts electrical energy into heat through the resistance of its components. When plugged in, the microwave's heating element creates resistance to the flow of electricity, generating heat to cook food.
How do heaters create energy?
Heaters do not create energy. Instead, they convert electrical energy into heat energy through a process called resistive heating. When electricity flows through a resistive element in the heater, the resistance in the element causes it to heat up and produce warmth.
What are some examples of radiation heat?
Radiation heat examples include sunlight warming the Earth, a campfire heating a person, and a microwave heating food.
Is ac better than dc for resistive heating?
no, heating is identical
What is an example of resistive load?
Some examples of resistive loads are: heaters, incandescent lights, fans etc.
Where does lost energy in a rheostat go?
It is lost in heating the resistive material of the rheostat.
What is the role of resistors in household appliances?
Probably the most common resistor in a household appliance is the resistive heating element. They appear in an electrical stove or range. The standard electric range and its oven have resistive heating elements in them. They're just "oversized" resistors that get really hot when we run current through them. Toasters have resistive heating elements, too. Most of the use nichrome in the form of wire or in little flat strips. Some have quartz heating elements, which have that resistive heating element inside quartz or fused silica glass. Coffee makers have resistive heating elements. Toaster ovens, too. Hair dryers and straightners? Yup. Anything that plugs in and is designed to get hot probably has a resistive heating element in it. There are actual resistors, like the electronic components, in all the electronic equipment in the house. All of it. They may be discreet components, or may be part of an integrated circuit. But they're there.

What type of load is elecric stove?
resistive load. I assume that the stove you are reffering is with heating coils.
What are two examples of ancient roman science?
The viaduct and under floor heating.
What is rear window defogger?
This is normally a resistive heating fixed to the inner surface of the glass of the rear screen.
What is another name for a cooker heating element?
Aga ? will this do? Edit: No idea what Aga is. Resistive element. Heating element. Heater. Burner. Do you care to specify the appliance?
