I recently did a question about DC circuit and I was confused by the answer given from the book. Can anyone convince that my answer is right?
Q) Suppose a single solar cell is capable of supplying exactly 81mW of DC power when exposed to direct sunlight. If 3 of these cells are connected in series, the resulting set of solar cells can theoretically provide
My Answer - 243mW of DC power in direct sunlight.
Text's answer - 719mW of DC power in direct sunlight.
I think the answer is 243mW because the current drawn from the cells are the same when they are connected in series. Recall that P = IV , so we have P = I(3V). Therefore, the total power supply by 3 cells is 243mW.
