What is input enerji?

Input energy refers to the energy that is required to operate a system or device. This energy can take many forms, including electrical, mechanical, or chemical. The amount of input energy needed will depend on the type of system/device and the specific task it is performing. For example, a computer may require electrical input energy to perform calculations, while a car requires mechanical input energy to move. The efficiency of a system/device is often measured by the ratio of the output energy (the energy the system/device produces) to the input energy (the energy it needs to operate). Minimizing input energy is important both for energy efficiency and for reducing the cost of operating the system/device.
