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.

How to write an actual algorithm for inserting an element in a linked list?
Insert newNode into a linked list after targetNode Node currentNode = root while currentNode != targetNode currentNode = currentNode.next newNode.next = currentNode.next currentNode.next = newNode
Why dont take out components with power supply on?
First of all, you should never open up a computer that is plugged in because of the risk of electric shock. Second, if you go pulling out parts while the machine is running, your hardware will most definitely be damaged.
When you press the space bar it makes a instead of a blank space?
My Computer has done this before too. It means that your computer has been on for to long and is over heating, if you leave your computer on over night. Then what you should do is turn it off while you sleep, turn it off when you are not using it, and after downloading or adding things to your computer restart it. I hope I helped. =]
What are sample sentences of alliteration in relation to computer science?
The moisture from the May Showers makes my motherboard moldy, and electric emptiness is always ejected to erroneous areas. The repeated consonants are alliteration, while the repeated vowel sounds are assonance. This is easy to remember because alliteration has two repeating "l" sounds, while assonance looks a lot emptier, like a vowel sound could be considered to be.
Which computer component presents the most danger from electrical shock?
The computer component that presents the most risk of electric shock is the power supply. Since there are large capacitors in the power supply, it is possible that you might get shocked, even with the power supply unplugged.Another component that presents a shock risk is an internal modem. You might grab a hold of it while there is an incoming phone call, and then get shocked from the ringer current.
What is the difference between water heater and calorifier?
The water heater has an electric heating element that is responsible to make the water hot if submerged to water. While the Calorifier is composed of steam coil where the steam from boiler passes through, is responsible to make the water hot if it get contact to the steam coil.
The cord of an electric oven does not glow while the heating element glows.Why?
The cord is manufactured to have as low a resistance as possible, while the heating element is intentionally manufactured with a carefully controlled resistance. The current through the whole loop ... cord plus heater ... is determined by the resistance of the whole loop. The magnitude of the current 'I' is (E/R) ... E = the utility line voltage, R = resistance of the cord+heater. But the power dissipated by each individual resistance in the loop is proportional to the resistance of that section. P = I2R. So the heating element dissipates more power than the low-resistance line-cord does.
Why does the chord of an electric heater not glow while the heating element does?
The element is made of special high resistance wire so the power is dissipated in the element rather than the low resistance cord.Power(watts) = Resistance (ohms) X {Current(amperes)}squared
Why thermistor is used in gas sensor TGS 2611?
It doesn't, allthough the resistive value is dependant on heater temperature the resistance of the sensor changes due to the presence of certain gasses (methane in this case) while the heater element itself facilitates a catalystic reaction in the sensor element. The temperature of the heating element is self-regulated and dependant on heater voltage.
What is the downside of electric floor heat?
While electric floor heating systems are great for heating, they generally fair poorly in cooling. Additionally, many contractors may not be familiar with an electric floor heating system setup.
Why does the cord of electric heater not glow while heating element does?
The cord is made of a very conductive metal, like copper. It has low resistance, so it there's not much energy lost and turned into heat from the cord. The heating element is a much less conductive material. It still conducts, but it has relatively high resistance, because the whole point is for it to turn electrical energy into heat. The heat raises the temperature of the element to the point where it begins to glow due to something called black body radiation, which is a kind of radiation that depends only on the temperature of the material.
Can I become immune to prednisone?
Why would your hot water heater water while it's heating but doesn't when it isn't
Why does the cord connecting to a room heater not glow while the the coil of the heater glows?
The wire in the cord is made of a very conductive metal, such as copper. Copper conducts electricity well, so not much energy is lost in transmission.The heating element will be made of a metal that isn't very conductive, so energy losses are high. This energy goes into heating the wires, and it's not uncommon for them to get red-hot in the process.
Why does your heater blows cold then hot then cold then hot?
It is because your heater is having to heat up so its blowing cold air out while its heating up.This means your heater is not very efficient and it needs to be checked.
How do you flush the heater system in a 1990 Thunderbird?
put cooling system flush in the radiator and follow the directions but make sure the heater is on while you do it.it will clean both your cooling and heating systems.
What is the power heat button in Toyota hilux?
This switch turns on an electric element inside the heater box so that you can warm your toes and defog the windscreen while the coolant temperature is rising in the engine. The idle speed does increase while the coolant is cold to compensate for the 25 amps or so that the element draws from the battery. As the coolant temp increases the element will switch off and the idle speed will go back to normal.
Can i put a water hearter element in place of a resistor in my plasma cutter?
A water heater element will burn out in a mater of seconds if you apply voltage to it while it is not submerged in water.
