If 2000j of energy is input to the kettle how much energy is output from the kettle?

The total energy in the kettle system will be 2000J. However, the energy will be distributed different ways. Some will go into heating the water, some will go into changing the water into steam (which takes a LOT of energy), and some will be lost as radiant heat energy. The specifics depend on the kettle itself, and how much water you have in the kettle.
Changing one milliliter of water by one degree requires 4.186 J of energy, but to convert it into steam requires 2259.36 J per ml

What is the relationship between energy input and energy output and energy losses whenever transfer of energy takes place?
Input energy = output energy + losses
How is energy efficiency determined?
You divide useful output energy by the input energy. Or equivalently, useful output power by input power.
What does efficiency compare energy output with?
With energy input
Does energy input always equals energy output?
Yes it does
What is the difference between input energy and output energy?
Input energy is when. . .say. . .you eat fruits or vegetables, and you get energy from them. You BRING IN energy or get energy. Output energy in when. . .say. . .you go run a mile or 2, and you use energy. You are PUTTING OUT energy.
What is the output input and process of a kettle?
Input is electricity and output is sound, heat and light.
Is energy input usually greater than energy output?
The energy input is always greater than energy output.
What is the relationship between energy input and energy output and energy losses whenever transfer of energy takes place?
Input energy = output energy + losses
How is energy efficiency determined?
You divide useful output energy by the input energy. Or equivalently, useful output power by input power.
Total energy input equals equals the useful energy output plus?
Efficiency = ( useful energy output / total energy input ) x 100
What does efficiency compare energy output with?
With energy input
What are the comparison of energy output with energy input?
Energy output refers to the amount of usable energy obtained from a system, while energy input is the amount of energy required to operate that system. A system is considered efficient when the energy output is greater than the energy input. Conversely, inefficiency occurs when more energy is put into a system than what is obtained as output.

A comparsion of energy output with energy input?
The result (ratio) of such a comparison is called the efficiency. Note that total energy output must be equal to energy input (conservation of energy); however, what is relevant for this comparison is the useful energy output.
What energy microphone output?
Microphones do not output anything, they are INPUT devices.
Is it possible for energy output to be greater than energy input?
No.
Efficiency of a motor?
ratio of energy output to energy input.
