An electric kettle is generally more efficient than an electric hotplate for boiling water. This is because electric kettles are specifically designed to quickly and efficiently heat water using less energy compared to a hotplate, which is a more versatile but slower option for heating water.

What is more powerful a 3KW electric kettle or a 10000W electric cooker?
10,000W is more powerful as 1KW = 1,000W. However, that is with EVERYTHING switched on, on the cooker - all element's, grill and oven - also a single element on a cooker is NOT likely to be more than about 1,500W (1.5KW) so therefore a kettle would be a lot more powerful for boiling water for example, be more energy efficent for that, and do it a lot faster.
Which has greater heat energy water tank of electric kettle?
The water tank of an electric kettle typically has more heat energy than a regular cup of water at the same temperature. This is because the electric kettle is designed to heat a larger volume of water to a higher temperature, thus storing more heat energy.
What is a sound physics reason for keeping a kettle polished?
Keeping a kettle polished can help prevent the formation of rust on the surface, which can affect the thermal conductivity of the material. By maintaining a smooth and polished surface, the heat transfer efficiency of the kettle can be preserved, allowing the water to heat up more quickly and evenly.
Why the heating element of an electric kettle is not placed in the middle of the kettle?
Placing the heating element at the bottom of the kettle allows heat to be directly transferred to the water, resulting in quicker and more uniform heating. If the heating element were in the middle, the water at the top of the kettle would take longer to heat up and there could be hot spots in the water.
What will happen if the heating element is near the top of an electric kettle?
If the heating element is near the top of an electric kettle, the water at the top will heat up faster than the water at the bottom. This can lead to uneven heating and potentially cause the top portion of the water to boil faster or even evaporate first.
What is kettle's efficiency?
Kettle efficiency refers to how effectively a kettle can convert electrical energy into heat energy to boil water. A kettle's efficiency can be influenced by factors such as the material of the kettle, its insulation, and the design of the heating element. Kettles with higher efficiency tend to boil water faster and use less electricity.

What is thermal efficiency of a kettle?
There are many factors that affect the loss of energy:1 the resistance of the wire2 the kettle will keep most heat in but not all heat within the kettle so more energy is lost3 the water will evaporate out the top and that is also a cause. (they can't close it off otherwise the pressure would build and it would explode).
What will happen if the heating element is near the top of an electric kettle?
If the heating element is near the top of an electric kettle, the water at the top will heat up faster than the water at the bottom. This can lead to uneven heating and potentially cause the top portion of the water to boil faster or even evaporate first.
Why and electric kettle switches it self off when the waterboils?
Electric kettles are equipped with an automatic shut-off feature, usually triggered by a heat-sensitive thermostat, to prevent the water from boiling dry and damaging the kettle. This helps ensure safety and prevents overheating, conserving energy and making the appliance more user-friendly.
How are electric cars different than hybrid cars?
Electric cars are electric, hybrids are gas, and electric.
How much water does the tea kettle hold?
An average teapot holds around 1.2 litres. Just if you want to know an average mug holds 220ml.
How long will the average cordless kettle last Is it the same as an electric coffee pot?
Cordless kettles will last a long time, especially if you're able to buy a stainless steel model. Cordless electric kettles are generally more durable than an electric coffee pot.
What is the efficiency of an electric generating plant?
I assume you're referring to the efficiency of converting heat energy into electricity. In general, 30-50%. This will vary depending on the design. Combined cycle plants will be more efficient.
