What is the total voltage when 12 Nickel-Cadmium batteries are connected in series?

When determining the total voltage of batteries connected in series, it is important to know the voltage rating of each individual battery. Nickel-Cadmium (NiCd) batteries typically have a nominal voltage of approximately 1.2 volts per cell.

In a series connection, the total voltage is the sum of the voltages of all the individual batteries. Therefore, if you have 12 NiCd batteries connected in series, you would perform the calculation as follows:

Total Voltage = Number of Batteries × Voltage per Battery

Total Voltage = 12 batteries × 1.2 volts/battery

Total Voltage = 14.4 volts

This means that the total voltage for 12 NiCd batteries in series is 14.4 volts, which is not listed among the choices provided. However, the choice of 15 volts may be a rough approximation in practical scenarios due to variations in battery voltage under load and other factors that could lead to rounding.

In summary, a more accurate assessment yields approximately 14.4 volts for the total voltage of 12 Nickel-Cadmium batteries in series, leading to the understanding that the original description might include a typographical error or misrepresentation of the context in which 15 volts might be considered a suitable answer in
