Want this question answered?
Input energy = output energy + losses
You divide useful output energy by the input energy. Or equivalently, useful output power by input power.
With energy input
Yes it does
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.
The energy input is always greater than energy output.
Input energy = output energy + losses
You divide useful output energy by the input energy. Or equivalently, useful output power by input power.
Efficiency = ( useful energy output / total energy input ) x 100
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.
the input isand the outpt is
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.
Microphones do not output anything, they are INPUT devices.
No.
ratio of energy output to energy input.
Yes it does
