What will happen if the heating element is near the top of an electric kettle?
The kettle will be less efficient because it won't be benefitting from the effects of convection currents. It will use considerably more energy.
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 tank must have a graeter amount of energy because it has to heat up more water there for it requirs more energy to do so
Does juice temperature increase with increasing convective heat transfer coefficient at any constant kettle surface temperature?
Yes, the juice temperature increases with an increasing convective heat transfer coefficient at any constant kettle surface temperature. The convective heat transfer coefficient represents the efficiency of heat transfer from the kettle to the juice. As the convective heat transfer coefficient rises, more heat is transferred from the kettle surface to the juice per unit of time. This increased efficiency results in a faster temperature rise in the juice. Therefore, a higher convective heat transfer coefficient enhances the overall heating process, leading to a greater temperature increase in the juice even when the kettle surface temperature remains constant.
Why a high-efficiency machine is more desirable than a low- efficiency machine?
High-efficiency machines do more for less and are therefore more desirable than a low-efficiency machine.AnswerHigher efficiency means lower energy losses and, therefore, such machines are more economical than low-efficiency machines.
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).

How are electric cars different than hybrid cars?
Electric cars are electric, hybrids are gas, and electric.
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.

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.
Which appliance in a home use the least energy?
The worst offenders are things that produce heat - such as an electic cooker, or a kettle. Next up are old inefficient lights. Finally consumer devices like Computers, TVs, DVD players.While the last group use the least electicity they tend to be left in a standby mode that still consumes electicity which means within a 24hr period your TV can easily consume more electricity than your kettle did...
Is a black kettle better than a white one?
A black kettle is preferred in the kitchen or camping, since it retains more heat than a white kettle.
