mlr: batteries, starting & charging - batteries overview (mlr) batteries overview (mlr) check for understanding 2 of 10 a 12 volt automotive battery contains how many cells? 6 cells 12 cells 2 cells 8 cells

Explanation:

Automotive batteries are typically lead - acid batteries. Each cell in a lead - acid battery has a voltage of approximately 2 volts. To find the number of cells in a 12 - volt battery, we use the formula \(n=\frac{V_{total}}{V_{per\ cell}}\). Substituting \(V_{total} = 12\) volts and \(V_{per\ cell}=2\) volts, we get \(n=\frac{12}{2}=6\).

Answer:

6 cells
