Final answer:
To make a virtual solar cell array with 6 A at 3 V using cards, one would arrange six cards in parallel (for 6 A) and then two sets of these parallels in series (for 3 V). The same number of cards can produce 18 W, with the setup depending on the desired voltage and current. Solar cells convert light to electricity, as seen in calculators with solar strips.
Explanation:
To create a virtual solar cell array with an output of 6 A at 3 V using cards that each represent a solar cell with an output of 0.5 V and a current of 2 A, you would need to arrange the cards in both series and parallel configurations. In this case, you would arrange six cards in parallel to achieve the required current of 6 A, since each card produces 2 A and 2 A times three is 6 A. To achieve the required voltage of 3 V with each card at 0.5 V, you would then connect two sets of these parallel arrangements in series (3 cards in parallel in each series group, two such series groups connected in series).
To achieve just 18 W without a specified voltage, you would not necessarily need more cards if you use the same number (six) of cards since 18 W is the product of the current and voltage (6 A × 3 V), which remains constant regardless of configuration.
A real-world example of a solar cell is the strip of solar cells above the keys on a calculator, which converts light energy to electrical energy for the calculator's use.
