What material are the plates of a wet cell NiCad storage battery made of?
AI Explanation
The correct answer is C) nickel hydroxide and cadmium oxide.
The plates of a wet cell NiCad (nickel-cadmium) storage battery are made of nickel hydroxide and cadmium oxide. This is the standard construction of NiCad batteries, which use these materials to store and release electrical energy through a chemical reaction.
The other answer choices are incorrect because:
A) Lead and lead peroxide are the materials used in lead-acid batteries, not NiCad batteries.
B) Potassium hydroxide and sulfuric acid are the electrolytes in NiCad and lead-acid batteries, respectively, not the plate materials.
D) Silver oxide and lead sulfate are the materials used in silver-oxide batteries, not NiCad batteries.
