Question:

A modeler wants to light his model building using miniature grain-of-wheat light bulbs connected in parallel as shown in Figure P2-23 . 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 \(500 \mu \mathrm{A}\) to preserve the batteries. If each light has a resistance of \(50 \mathrm{k} \Omega\), how many lights can he install and still be under his current limit?
