17) Most 12 V car battery are made up of six individual cells connected in series. What is the voltage of each cell in a car battery?

1. 2 V
2. 3.5 V
3. 6 V
4. 12 V

Voltages in series are added to determine the total voltage, so divide 12 volts by 6 cells to get 2 volts.

To be exact, each cell in a car battery provides 2.1 volts for a total of 12.6 volts when connected in a series and at full charge.
