Because Heat is Directly Proportional to Resistance Of Element
AnswerPower is inversely, not directly, proportional to the resistance of a heating element.
So, the higher the resistance, the lower the heating effect. For example, a 'high-wattage' lamp has a lower resistance than a 'low-wattage' lamp.
This is because power is equal to the voltage squared divided by resistance; so, the lower the resistance, the more powerful (and, therefore, the hotter) the heating element.

Which part of the electric stove produce the heating effect?
A heating element. That is made out of high electrical resistance material. As electricity pass through the element a high amount of resistance is encountered, thus heat is created.
What properties are needed for the heating element of an electric iron?
The heating element of an electric iron needs to have high electrical resistance, good heat conductivity, and resistance to oxidation. Additionally, it should be durable and able to reach and maintain high temperatures to effectively iron clothes.
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 can I test the dryer heating element to determine if it is functioning properly?
To test the dryer heating element, you can use a multimeter set to the ohms setting. Disconnect the dryer from the power source and locate the heating element. Remove the wires connected to the heating element and place the multimeter probes on the terminals of the heating element. If the multimeter reads a low resistance, the heating element is functioning properly. If the reading is high or infinite, the heating element may be faulty and needs to be replaced.
What components make up a heating element?
Usually Nichrome, as it has very high resistance and does not oxidize in its usual temperature range.
Which heating element is used in a heater?
The most common heating element used in heaters is a resistive heating element, usually made of materials like nichrome or ceramic. This element heats up when an electric current passes through it, generating heat that warms the air around it.
Would a wood- burning tool work well if its heating element had a very high resistance?
A wood-burning tool relies on its heating element to generate sufficient heat for burning wood, which requires a lower resistance to allow higher current flow. If the heating element has very high resistance, it would restrict current flow, resulting in insufficient heat generation. Consequently, the tool would likely be ineffective for wood burning, as it wouldn't reach the necessary temperatures to burn the material effectively.
Which type of substance would you use as a heating coil in an electric toasters?
I believe I would select NiChrome wire. It has a high resistance for a metal and is not particularly toxic or expensive.
Why tungsten is not as heating element in iron box?
Tungsten is not commonly used as a heating element in iron boxes because it has a very high melting point, which would make it difficult to work with and shape into the required size and configuration for the heating element. Additionally, tungsten is quite expensive compared to other materials commonly used for heating elements, making it less economical for this application.
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
How glue gun heating element works?
A glue gun heating element consists of a metal rod wrapped with a high-resistance wire, such as nichrome. When electricity passes through the wire, it generates heat due to electrical resistance. This heat is transferred to the metal rod, which then heats up the glue stick in the gun to melt it for application.
What is the use of universal high resistance voltmeter?
A voltmeter must have a very high resistance to measure voltage. A voltmeter is placed in parallel with the element that you are measuring. If the voltmeter has a low internal resistance, then all of the current will flow through the voltmeter instead of the element. You want all of the current to flow through the element, to get an accurate reading of the voltage. Conversely, an ampmeter must have zero resistance, because it is placed in series with the element.
