Question

A car battery produces 12 from electric that each produce 2.0 V. What is the minimum number of electric cells in car battery?

Answer 1

6

Step-by-step explanation:

From the given question, since a total of 12 V was obtained from the battery which is made up of a number of cells with each producing 2.0 V.

Assuming that the cells have a very low internal resistance, then;

minimum number of electric cells in the car battery =
`(total voltage from the cells)/(individual voltage of the cells)`

=
`(12)/(2)`

= 6

Thus, the minimum number of electric cells in the car battery is 6.

This implies that the addition of 6 cells which has 2.0 V supply in the battery produces a total of 12 V. Provided that the cells have a very low internal resistance.
