FCC Exam Question: 3-60I4

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

A. 12 volts.
B. 12.6 volts.
C. 15 volts.
D. 72 volts.
Correct Answer: C

Explanation: When batteries are connected in series, their individual voltages add together to produce a total voltage. A single Nickel-Cadmium (NiCd) cell has a nominal voltage of 1.25 volts. To find the total voltage for 12 NiCd batteries in series, multiply the number of cells by the voltage of each cell: Total Voltage = Number of cells × Voltage per cell Total Voltage = 12 × 1.25 V = 15 volts. Therefore, option C is correct. Options A and B are incorrect because they do not reflect the standard 1.25V per cell for NiCd batteries. Option D is significantly too high, implying an incorrect voltage per cell.
