231 A modeler wants to light his model building using miniature grain-of-wheat light bulbs connected in parallel

Question:

2–31 A modeler wants to light his model building using miniature grain-of-wheat light bulbs connected in parallel as shown in Figure P2−31. He uses two 1:5-V “C-cells” to power his lights. He wants to use as many lights as possible but wants to limit his current drain to 500 μA to preserve the batteries.

If each light has a resistance of 50 kΩ, how many lights can he install and still be under his current limit?
