Question

Which of the following best describes the operating principal in a nickel - cadmium battery installed in an aircraft?

A) At full charge, the electrolyte will be at its lowest level and should be filled
B) To completely charge a nickel - cadmium battery, some guessing must take place; thus, some water will be used
C) When positive plates slowly give up oxygen, which is regained by the negative plates, the battery is charging

Answer 1

The operating principle in a nickel-cadmium (NiCad) battery is the movement of oxygen between the positive and negative plates during charging and discharging. This process allows the battery to store and release energy as electricity.

Step-by-step explanation:

The operating principle in a nickel-cadmium (NiCad) battery installed in an aircraft can be explained by the reactions that occur during charging and discharging of the battery. During charging, the positive plates give up oxygen and the negative plates regain the oxygen. This process allows the battery to store energy. On the other hand, during discharging, the chemical reactions reverse and the nickel and cadmium ions combine to create electricity that powers the aircraft's systems.
