We kick the pedals of the bi-cycle. The energy given by us on the system is called input energy. Now the cycle moves through a distance. This is the out put energy that we get from the system. The ratio of the out put energy to that of input is defined as the efficiency of the system.
The energy input is always greater than energy output.
The input means the problem and the output means the answer! [but not in math]
Input energy = output energy + losses
You divide useful output energy by the input energy. Or equivalently, useful output power by input power.
When energy input exceeds energy output, it means that all the energy taken into the body is not being used. This energy can be converted into fat, causing a person's overall mass to increase. In order to make sure that the energy input does not exceed the energy output, a person must ensure that they are getting enough physical excercise. Remember that energy is used in normal metabolic processes as well, concluding that exercise is not the only component that contributes to energy output.

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.
