The nominal voltage of one cell of a wet cell nickel-cadmium battery is approximately how many volts?

Correct Answer: Option A — 1.2 volts

Nickel-cadmium (Ni-Cad) storage batteries utilize an alkaline potassium hydroxide electrolyte. The chemical reaction across the active materials yields a lower nominal cell potential than lead-acid types, specifically standardizing at approximately 1.2 volts per cell.
