Does the wire in the electrical cord of an electric kettle 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.
The sudden heating and cooling of air causes what?
It causes tornadoes
Heating causes an object to?
expand
Two examples of resistive heating?
An incandescent light bulb. An electric heater. A simple resistor. Basically most things that heat up when a current is passed through them do so due to the resistive nature of the load.
Why is shiny metal fixed to the back of an electric bar fire?
It is shiny because it will keep the fire hot.
Is ac better than dc for resistive heating?
no, heating is identical
What causes heating effect when current flows?
The resistance factors to the current flow in the circuit is what causes the heating effect in a circuit. This resistance usually comes from the load that is connected to the circuit. For example a baseboard heater is a completely resistive load and the result of the heating of the device can be used to heat a room in the home.
What does fire restitive mean?
Something that is not easy to light on fire is fire resistive.
What is the major difference between noncombustible construction and fire resistive construction?
Basically non combustible and fire resistive are the same. Difference is non combustible has steel frame members that are unprotected or limited protected. Fire resistive has protected steel frame members with a fire rated material such as concrete.
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 structure is fire resistive?
Type your answer here... asbestos
What type of load is elecric stove?
resistive load. I assume that the stove you are reffering is with heating coils.
Is brick considered fire resistive?
Yes, heat just hardens them
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?
What is rear window defogger?
This is normally a resistive heating fixed to the inner surface of the glass of the rear screen.
Is an open fire or closed fire best for heating a house?
The answer is that a closed fire is best for heating a house.
