Question 239Electricity & Electronics - Assistant Engineer

The correct answer is A) 1.2 volts. The approximate discharge voltage produced by one cell of a wet type nickel-cadmium battery at 75% of charge is 1.2 volts. This is the standard voltage for a nickel-cadmium battery cell, which typically ranges from 1.2 to 1.25 volts when fully charged and drops to around 1.2 volts at 75% charge. The other answer choices are incorrect because 1.5 volts is the voltage of a lead-acid battery, 2.2 volts is too high for a single nickel-cadmium cell, and 6.0 volts would be the voltage of a series-connected battery pack, not a single cell.
