answer:- The correct answer is D)414.

Solution:- From given information, one cell contributes 14.5 W. We need to calculate the number of cells that would produce 6 kW of power.

We know that, 1 kW = 1000 W

Convert Given kW to W and divide by the power of one cell to calculate the number of cells required. The set is made as:


6kW((1000W)/(1kW))((1Cell)/(14.5W))

= 414 cells

So, 414 cells need to be there in the stack to produce 6kW of power.
