This document discusses two electronic components: light-emitting diodes (LEDs) and light dependent resistors (LDRs). LEDs are semiconductors that emit light when current passes through them and are commonly used as indicator lamps. LDRs are resistors whose resistance decreases when exposed to light, allowing more current to flow. The document contrasts how LEDs allow current to flow in one direction when emitting light, while LDRs resist current flow but conduct more when light hits them.
