Input is bread.Process is heat.Output is toast.
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.
