Answer the following questions. Please I really need help. Even if you write something easy, I beg you.

Explain in your own words how the Battery testing (performance test) is applied to the patient turning apparatus shown in the figure, and guess how the expected result will be.

In addition, there are heating pads working with the logic of electric blankets in this apparatus but consider that it works with a battery, not a plug. Please answer by taking these into account when answering.
