Question

"A series stack of alkaline cells produces 4.524 kW of power. If each cell contributes 14.5 W, how many cells are in the stack?"

How many cells are in the series stack?

a) 3

b) 66

c) 312

d) 3,205

Answer 1

To calculate the number of cells in the series stack, divide the total power produced by the power contributed by each cell. Given that each cell contributes 14.5 W and the total power produced is 4.524 kW, there are 312 cells in the series stack.

Step-by-step explanation:

To calculate the number of cells in the series stack, we can divide the total power produced by the power contributed by each cell. Given that each cell contributes 14.5 W and the total power produced is 4.524 kW (4524 W), we can use the formula:

Number of cells = Total power / Power contributed by each cell

Number of cells = 4524 W / 14.5 W

Number of cells = 312

Therefore, there are 312 cells in the series stack.
