You have purchased a ‘smart phone’ which has a battery system advertised as allowing 22 hours of ‘talk time’ before it requires recharging. A friend of yours advises you that it is a good phone, but the 22 hours of ‘talk time’ is a highly theoretical number, based on ideal conditions concerning the placement of the phone towers around you as you talk, the exact number of calls you initiated while talking, and the state of the battery when you last charged the phone. As a result of these issues, your friend warns you that you can generally only expect 20 hours of ‘talk time’ from the battery system. Based on this discussion with your friend, the issue concerning the actual placement of the phone towers around you as you talk is best described by which of these concepts? a. the effective capacity of the phone battery system b. a point of indifference in the phone battery system c. the utilization of the phone battery system d. the design capacity of the phone battery system e. a determinant of the effective capacity of the phone battery system

This is an example of "THE UTILIZATION OF THE PHONE BATTERY SYSTEM". Therefore option "C" is the most correct option.

Explanation: Because the phone battery has been analysed due to the maximum satisfaction that can be derived form it, that means the utilization of the phone battery system has been checked.

Since the maximum utilization you will derived from the phone is how long the battery duration will last during call hours, therefore you have checked the utilization of the phone battery.

The efficiency of the phone battery will be the same if the phone is not utilized, and different if the phone is utilized in differents ways. Therefore phone users analyse phone battery with the utilization their want to derive from the phone. Another person's utilization can be how long the phone battery can last while chatting or playing music.
